John Cho is David Kim lost his wife to lymphoma. He is the single parent of a teenage daughter Margot (Michelle La). One night, she tells her Dad that she is studying for biology finals at a friend’s house, and then she goes missing. To help investigate the case, Detective Vick (Debra Messing) joins the case. What sets this story apart from other missing teenager films is that it is told almost entirely through technology. Kim mines content on his daughter’s computer from apps such as Tumblr, Facebook, and Instagram as well as text messages to try to figure out what happened to his daughter and soon discovers how little he knows about her. The story feels very contemporary, the acting is great, and there are enough twists and turns to keep the story fresh and interesting. I liked the end and found it heartbreaking, but it also felt like it needed more development. Thumbs up for a film that is suspenseful and will likely resonate with parents of teenagers as well as those with an interest in technology. The movie kept me captivated all the way through.
