I Trapped the Devil (2019)

Description

Married couple Matt and Karen visit Matt's troubled brother Steve during Christmas unannounced. Steve, who occasionally sees visions through television static and receives disturbing phone calls, at first insists they leave. When they refuse, Steve shows Matt and Karen a padlocked door bearing a cross in the basement. Matt and Karen hear a man's voice call for help, and Steve claims his prisoner is the devil. Steve dodges questions about details by saying that something evil conjured itself into the shape of a man, and he trapped it behind the door.
