The film stars Gillian Jacobs, John Gallagher Jr., Azhy Robertson, and Winslow Fegley.

A gruesome monster named "Larry" manifests itself through smart phones and mobile devices while trying to take Oliver, a lonely boy desperate for a friend.

He attends school and is mostly taken care of by his mother, Sarah; his father Marty spends most of his time at work trying to make ends meet.

One night at work, Marty is attacked by Larry, who can travel through electricity and usually communicates with people through screens.

Sarah trashes all electrical devices in the house, but the TV finishes playing Larry's story before she can shut it off.

Larry takes physical form, being able to move in real life without the use of a screen, and begins to stalk them throughout the house.

Marty grabs his phone and sees Oliver and Sarah (who has been taken by Larry and seemingly lives in his world) playing happily.
