Overview

For 49-year-old Jane, Summer should be about work, love, and weekends out at the sea. However, it is impossible to leave her house because she has so many confusing locks on her door. But after a seemingly innocent deadbolt lock installation, she finds herself plagued by strange visions and the inescapable sense that someone, something, is behind the door. Faced with this burden, Jane must find a way to escape the horrors that seem to be only a few steps behind. Unfortunately for her, the deadbolt opens from the outside, so the killer enters her home.
