Irish journalist Martin Barry was only 30 years old when he died at the Dignitas Clinic in Zurich, accompanied by his ex girlfriend Laura McDaid.

The night before he died, he asked Laura to fulfil his last request: to track down his birth mother and pass on a message.

Martin had been born in a mother and baby home in Co. Cork in Ireland. He'd never met his birth mother.

Twenty years later, along with her producer Kerry Jamison, Laura embarks on a search that will take her from the top of this island to the bottom and across the Irish sea, to fulfil the promise she made to Martin.

BBC reporter Laura McDaid held Martin Barry's hand as he died at the Dignitas Clinic. 17 years later, she begins a search to fulfil his last request: to find his birth mother and pass on a message.

To move forward with the search, Laura first needs to explain why it's taken her 17 years to have the strength to search for Martin's mother.

She takes Kerry back to the aftermath of Martin's death, and how it was handled by the press at the time.

Will the records provide her with any further information?
