On a misty morning in the Lake District, two men depart by helicopter from a private estate. Below, they see the stunning views of Wast Water, with Scafell Pike ahead, where fell runners are competing atop England’s highest mountain. It’s at this moment that the pilots lose control, and crash into the mountain top. Runners and bystanders are caught in the devastation.

This is the scene that greets DI Kelly Porter. She attempts to coordinate the rescue efforts, though it’s clear many won’t make it, including occupants of the helicopter. Three are dead, and the fourth is badly injured. When it emerges that the survivor is none other than the Right Honourable Lord Donald Reilly, and the person who chartered the flight was notorious billionaire Bartholomew Kennedy-Craig, the media frenzy is intense. Reilly is high up in government, and his contact with the magnate provokes speculation.
