Lifelong friends Liza and Molly have grown distant since Liza moved to Chicago. One night, when Molly’s husband Daniel is away on business, they have a video chat in a bid to reconnect. After an awkward start, the conversation is flowing easily when Molly has to go check on one of her children. Liza is horrified when she sees a masked man enter her friend’s house, and panics when the screen goes dark. She calls the police, and then—unable to get Molly to answer her phone—Liza jumps in her car and drives all night to make sure she is okay, only to be turned away by an angry Molly. Confused, hurt, and angry, Liza returns home only to find more heartbreak waiting for her as she tries to figure out what happened that fateful night.
