It’s supposed to be a place of thrills, laughter, and unforgettable memories. But in summer 2015, an afternoon at Alton Towers, turned into a living nightmare. 

One rollercoaster - The Smiler - came to a catastrophic halt and what followed was one of the most serious roller coaster accidents in UK history. 

It was supposed to be the trip of a lifetime - a solo adventure across the world. About to turn 22, Grace Millane had her whole life ahead of her. But what began as a night out in Auckland, would end in silence. A missing persons report, and a journey cut brutally short. 

Morgan Metzer slipped away early from the New Year's Eve celebrations. 

She wasn’t in the mood to celebrate - it had been a tough year. 

She would happily trade the noise of fireworks for the quiet comfort of her own bed. 

The night should’ve ended peacefully. But she had no idea of the terror that was about to unfold, right there in her home. 

A figure dressed in black was watching.. and waiting. 

She vanished without a trace… leaving behind a series of messages that painted a picture of fear, confusion, and someone clearly in distress. In the hours before she disappeared, something wasn’t right. She was asking for help, running from something, or someone. And when her body was finally found, the question wasn’t just what happened to Gaia Pope… but who or what had she been so afraid of?

She became one of the most talked-about faces on TV — the centre of a show built on shock, secrecy, and a twist that left viewers stunned. But when the cameras stopped rolling, things got even darker. 

Years later, her story would end in circumstances so disturbing that people still question what really happened. This is the haunting story of the rise and fall of a beautiful reality star whose fame came at the ultimate price. 

It started out as a simple psychological study.. 

What would happen if a bunch of students played prisons?

But The Stanford Prison experiment spiralled so far out of control that the stories are still told to this day in lecture halls.. over 50 years on. 

The experiment posed the question.. are we really all capable of evil? In certain circumstances.. how far are we willing to go?

It looked like an ordinary house in an ordinary neighbourhood. But at the bottom of the staircase, was a body. A man facedown at the bottom of his stairs. A huge pool of blood and one looming question - accident or murder? This is the unsettling case of Kevin Davis

Las Vegas is the home of nightlife. Bright lights, big city. It'ss the city that never sleeps. But what happens when the dream turns into a living nightmare? What if someone was watching you.. waiting.. to strike when you least expected. This is the terrifying case of Shauna Tiaffay

A missing persons report.. an empty house.. and the smell of bleach. It doesn’t sound promising. But in cases like these, police need to go off more than just a hunch. What do you do when EVERYTHING is pointing to one suspect.. but they’re denying doing anything wrong?

This is the mysterious case of Lorraine Garcia. 

The first clue wasn’t a scream. It wasn’t a missing persons report. It was a black bin bag.
In the early hours of the morning in Camden, a grim discovery was made.  And in that moment, an ordinary London street became the centre of one of the most disturbing murder investigations the city had seen in decades.

This is the case of the Camden ripper.
