Charlie Jordan is being driven across the country by a serial killer. Maybe.

Behind the wheel is Josh Baxter, a stranger Charlie met by the college ride share board, who also has a good reason for leaving university in the middle of term. On the road they share their stories, carefully avoiding the subject dominating the news - the Campus Killer, who's tied up and stabbed three students in the span of a year, has just struck again.

Travelling the lengthy journey between university and their final destination, Charlie begins to notice discrepancies in Josh's story.

As she begins to plan her escape from the man she is becoming certain is the killer, she starts to suspect that Josh knows exactly what she's thinking.

Meaning that she could very well end up as his next victim.

A game of cat and mouse is about to play out. In order to win, Charlie must do only one thing . . . survive the night.
