A boy named Kevin (Lucas Paul) suffers a head injury. He and his sister, Kaylee (Dali Rose Tetrault), cannot find their father (Ross Paul). There are several windows and doors in their homes, and then none. They set up camp in the downstairs TV room with loads of old fashioned cartoons. An apparently malevolent, supernatural presence has set up camp on the top floor, where their bedroom and their parents' room are located. Two children wake up in the middle of the night to find their father is missing, and all the windows and doors in their home have vanished.
