Private detective Cassie Dewell partners with ex-cop Jenny Hoyt on a search for two sisters who have been kidnapped by a truck driver on a remote highway in Montana. When they discover that these are not the only girls who have disappeared in the area, they must race against the clock to stop the perpetrator before another woman is taken.

It follows a career-oriented girl whose priorities have always been clear for her, even if it compromises the things she really wants to do. When a typhoon worsens while she's at work, she finds herself trapped inside the building with a food delivery guy, whose background is also more complicated than he looks. While stranded, the two learns more about each other's lives, and soon will also learn some things about themselves and their feelings.
