In the idyllic seaside town of Cayucos, on the Californian coast, property is expensive, a home here can easily cost a million dollars or more. The property boom which has made people of Carolyn’s generation well off, has priced so many out of the market and made it expensive to rent. There is a growing problem with homelessness, a world that Dave knows well. Even now that he is living with Carolyn he has not cut his ties with the homeless and is determined to help when he can.

When Dave returns to Riverside, on the outskirts of Los Angeles, he visits some of the friends he lived alongside on the river bottom. There are tarpaulin covers stretching for miles, largely hidden by the trees and it is down there that we meet Rebecca. She is a crystal meth addict and offers him the pipe: he has made so much of leaving this world behind, but has he really?

In that same visit he goes back to the Gavilan mountains, a spaghetti Western landscape that is sun scorched and inhospitable. It was here that Dave lived with a famous Hollywood actress. A story which hardly seems true but which is and one which quickly raises new worries about Carolyn’s safety at his hands.

The relationship between Dave and Carolyn captured the attention of the BBC Journalist Sue Mitchell, an investigative journalist who reports on the lives of people like Dave who inhabit the dangerous margins of society.

At first glance Carolyn appears to be a lucky woman who has led a charmed life: loved by her husband and daughters – prosperous and secure. But she has endured great hardship and in this episode it becomes a bit easier to understand why she initially felt so drawn to Dave and what he has come to represent in her life.

For his part, Dave is reluctant to dwell on his childhood, but he undoubtedly had a difficult start in life. Some of that damage has since been repeated in the lives of his children and grandchildren. As the bond between Carolyn and Dave deepens, she is clear about wanting to protect his future by helping him financially.

Relationships in your later years are never going to be plain sailing: there are usually long established patterns, and problems to contend with. Carolyn is on her own with these now that her daughters have been pushed to the side-lines of her life. She is struggling to drive at night and to do her tax returns and she is increasingly frustrated with Dave’s drinking and socialising

The story captured the attention of the BBC Journalist Sue Mitchell as it was unfolding on her street. She spends a lot of time in California, she married an American and her award-winning journalism has been about the lives of people like Dave who inhabit the dangerous margins of society.

With Carolyn’s encouragement, Dave is making more effort to see his children, including his daughter, Cody. Like her Dad, Cody has struggled with crystal meth addiction and is sometimes sleeping rough in her car as she waits for a place in a recovery unit. She longs for her Dad’s love, but she has been let down by him in the past and cannot really trust that he has changed

In this episode BBC Journalist, Sue Mitchell, goes with Dave to Riverside, on the outskirts of Los Angeles. This is where Dave has spent a lot of his life and on a walk at a local landmark he discloses that it is also where he was locked up following a violent attack. As more secrets from his past emerge Sue catches glimpses of Dave’s anger and of his more sinister side.

The revelations go to the heart of the question everyone in Cayucos is asking: is Dave really a tender carer who will cherish Carolyn to the end as he promises, or is he a dangerous interloper who will fleece Carolyn – breaking her heart and her family?

One of the consequences of the family falling out about Dave is that Carolyn has decided to take back control of her bank accounts from her daughter, Sally, who had always helped her Mum in the past. Carolyn’s daughters fear that she will start giving money to Dave and that there is nothing they can do about it.

In the early days of the relationship, the daughters had got Carolyn and Dave to sign a legal agreement protecting her money and properties. But now they fear that the pair have effectively ripped up that agreement, which they are perfectly entitled to do. Could this be the start of the nightmare scenario they have been dreading ever since Dave moved into the family home?

There is a childlike quality in Carolyn when it comes to Dave that does make her vulnerable. She guards him as if he is some kind of rare treasure and when he is out late drinking with friends, she sometimes sets out in the dark to find him. Her neighbour Marie, who cares for more than a dozen wealthy old women in Cayucos, says it is something she sees a lot.

Marie warned Carolyn about Dave, but to no avail and soon she is pushed to the side-lines of Carolyn's life, powerless to act. With people in this idyllic Californian community left wondering whether Dave really a tender carer who will cherish Carolyn to the end as he promises, or is he a dangerous interloper who will fleece Carolyn – breaking her heart and her family?

Carolyn is facing mounting opposition to her relationship with Dave, who is 23 years younger than her and a world away in terms of wealth and lifestyle. She is being forced to make the most difficult choice possible: between her daughters and her new lover. The situation becomes so heated that it finally erupts into violence.

Opposition to Dave makes Carolyn more determined to support him and she decides to take back control of her finances from her daughters. They fear she is showing signs of mental incapacity and want her to agree to be tested, but Carolyn is digging her heels in and is adamant that she can make her own decisions

The situation is escalating really quickly, with her daughters are increasingly on the side-lines - powerless to act. They have huge concerns about Dave, who has a long criminal record and was homeless and addicted to the drug, Crystal Meth. They cannot get their Mum to listen and as long as she says she is happy, there appears to be nothing that they can do.

Million Dollar Lover is an unlikely love story, recorded over a year as the relationship unfolds between Carolyn, who is 80 and has a valuable property portfolio, and Dave, 57, who arrives in the idyllic Californian resort of Cayucos by chance and quickly decides to make it his home

Carolyn had not expected to fall in love at 80 and certainly not to someone 23 years younger. But she has embraced all aspects of her new relationship, including having sex and being open with her daughters about that. Her honesty has not gone down well and even her Pastor, Dale James, is shocked that the couple are now living together in this way.

Concerned about the speed of the relationship and the direction it's taking, Carolyn's daughters turn to the police and outside agencies for help. They believe their Mum is in the early stages of dementia, but her GP did not support their diagnosis and now Carolyn will not go back for further tests. Their options for stopping Dave taking control of their Mum's life appear to be limited and they fear what might happen.

Million Dollar Lover is an unlikely love story, recorded in real time as the relationship unfolds between Carolyn, who is 80 and has properties worth a few million dollars, and Dave, 57, a former drug addict who is homeless and has spent a decade in jail.

The story captured the attention of the BBC Journalist Sue Mitchell, as it was unfolding on her street. She spends a lot of time in California – she married an American and her award-winning journalism has been about the lives of people like Dave who inhabit the dangerous margins of society.

There are so many homeless people in America that the wealthy can no longer avoid contact with them. When Dave arrives in Cayucos, a charming beach town, prosperous and sunny all year round, he goes to church. Some people there try to help him find work and recommend him to Carolyn as an odd job man. She falls in love with him and within a fortnight, Dave has moved in.

Dave is a talented man – a skilled joiner and musician who makes and sells jewellery. With Carolyn’s support, he is ambitions for his future. He appears to be thriving and so does she. But she is vulnerable following the death of her husband. Her family fear she is showing signs of cognitive decline and she certainly struggles to manage her finances. She also yearns to feel the love that comes from a romantic relationship and to feel needed again.

Her neighbour, Marie, says it is something she sees a lot amongst the elderly people she cares for; it is a desire to be loved and to be in love which does not diminish with age. Marie cautions Carolyn against rushing into a relationship with Dave, but it is too late. Soon Marie is left watching from the side-lines as Carolyn starts cutting off friends and relatives who question her.

Her middle-aged daughters are increasingly worried for their Mum and for the money they expected to inherit from her; a property portfolio which their parents and grandparents had built up over the years. They fear Dave might be taking advantage of Carolyn and ask her to be assessed for mental incapacity: it seems the only explanation they can find for why she has fallen so deeply under his spell.

Sue Michell is a skilled investigator who uncovers horrors in Dave’s past that he has never mentioned to a living soul. She also brings her knowledge of elder abuse and exposes how the process of ageing makes subtle changes that can alter how we see others - particularly strangers who seem loving, young, and strong.

Is Dave really a tender carer who will cherish Carolyn to the end as he promises, or is he a dangerous interloper who will fleece Carolyn – breaking her heart and her family?

The idea of living forever has captivated us for millennia, but rarely do people imagine what would happen the day after the fountain of youth is discovered. Today’s technology entrepreneurs pushing an immortality agenda - through their investments and their influence - seem only focussed on the pursuit.

Whether or not immortality is a distant possibility, how do we cope with living longer en route to forever? Where’s the planning for that? It’s a great opportunity for innovative thinkers but, from what we’ve seen over the last two decades of technological disruption, these real but smaller goals aren’t nearly as enticing as the big ones.

In this series, technology reporter and psychologist Aleks Krotoski explores the frontiers of the extreme longevity pioneers. They've made their money in Silicon Valley. And with their technology solutions - PayPal, Facebook, cryptocurrencies - they've ushered in the world that we live in today, with all its unintended consequences. Some of them now want to solve the "problem" of aging, or even death, and they are making bigger strides than we may think.

Can they? Should they?

The immortalist movement in Silicon Valley shares a lot with evangelical religions, says Dr Emile P Torres, a philosopher and former Nick Bostrom acolyte. In both, he explains, there’s a heaven in which the faithful will experience unsurpassed bliss and delight, and an apocalypse, which will separate out the people who can go there.

After a decade at the epicentre of the transhumanist research community, Emile became concerned with the number of apocalyptic stories of techno-utopia that were being shared online. Was this philosophical movement becoming radicalised? When Emile raises the question, the consequences are swift and severe. Excommunicated, harassed and threatened.

With influential and powerful technology billionaires as some of its faithful, is Emile right? Is this movement really one of the most dangerous secular ideologies?
