UNKNOWN

A private detective, down on his luck. A bus crash in the middle of nowhere. A murderer, hiding in plain sight. When Sydney Cartel investigates a murder, he usually stands on the other side of the police tape. Trying to escape the limelight of his career, he boards a night bus in rural southern Britain.

But when the bus loses control and falls into a valley, Sydney and the survivors scramble to find shelter at a local inn by the side of the road. In the dead of night, with a storm preventing anyone from getting in or out, the survivors of the crash prepare for a long stay at the Roadside Inn, finding comfort and solace in each other's company.

Then, they find the first body. Locked in by the storm, the once-famed detective finds himself in the middle of a murder investigation, where any one of the survivors is a potential brutal killer. One by one, the killer does away with another one of the inn's guests.

Who's behind the murders? Was the crash truly an accident? And is it truly just a coincidence that Sydney happened to be on board that bus, or is the killer just toying with him?

The clock is ticking. Can Sydney track down the killer and get to the bottom of the murders before he becomes a target himself?
