John Cho stars as a widower father whose life gets turned upside down when his teenage daughter goes missing. As he goes online to search for clues to her whereabouts, he discovers that the close relationship he thought he had with her may not have been as tight-knit as he was led to believe. Debra Messing co-stars as the missing-persons detective on the beat in this nifty thriller that sets all of its actions on the screens of a variety of computer devices.
The entirety of the film is the view from the laptop screen of teenager Blaire Lily,whose very private Skype conversation with boyfriend Mitch is rudely interrupted by a trio of friends looking to chat up the clique. It’s the first anniversary of the suicide of their classmate, Laura, who offed herself after being cyberbullied following the posting of a dreadfully embarrassing video of her on YouTube. When a sixth participant in the group chat appears, and Blaire begins to get private messages on Facebook from Laura’s dormant account, she immediately suspects one of them is playing some sort of very sick joke. Or, perhaps it is a malicious hacker. Or, perhaps worst of all, could it truly be Laura contacting them from beyond? If so, they’re all in trouble, as they’re told they will die if they leave the chat, and “Laura” has a lot of information to expose about them all they wouldn’t want anyone to know, especially within that very clique of friends.
