16 and Missing (2015)

Widower Daniel and model son Brandon's happiness with his second wife, a retired FBI agent, is poisoned by her spoiled-rotten, ever-hostile teen daughter Abbey, who once survived a kidnapping during which her father was fatally shot. Abbey confide only into more sensible buddy Janelle her hair-brain scheme to runaway to Arizona for her pen lover, handsome young cop Gavin. It soon becomes clear to the home-front, earlier the her, that Gavin is an alias assumed by ex-con Wesley, who has a deep, dark motive.
