Shift (1970)

Tom, a Steve Buscemi type with less drive, takes the night job at Your Storage in Washington Park, Chicago, armed with security monitors, lackluster wit, a late-night radio DJ, and his trusty office chair, Grace Kelly. He’s there to shut out the world and ignore his family drama when the usually easy gig takes a sinister turn. A typical regular, Mrs. Jones, lures an unsuspecting man into her storage unit-a man that Tom never sees again.
