New friends Sam, Margaret and Diana are thrilled to be getting out of the city for a girls' weekend-they've bonded over their messy divorces, and every mile on the odometer feels like another step towards putting their exes in the past. But when car trouble halfway into their trip strands them in the most unlikely of mountain towns, they come face-to-face with the hurts and betrayals they were so desperate to leave behind.

When Diana doesn't return home after a night out, Sam and Margaret's search for her reveals just how little they know about their friend. As eerie coincidences and secrets begin to pile up, and an ex-boyfriend arrives in the tiny town, the women realize that their detour may not have been a mistake...and that someone wants to guarantee that they never make it out.
