The Shelter (2015)

On a star filled night, widower and homeless man Thomas (Michael Pare) finds shelter for the night when he falls upon a vast two story house with the lights on and an inviting open front door. Alas the next morning he finds out swiftly that the premises won't let him depart. The doors are all locked, and the windows puzzlingly cannot be opened or broken. Destiny has brought Thomas to this place. Will he survive the ordeal?
