Lady in a Cage

When an electrical power failure occurs, Mrs. Hilyard (Olivia de Havilland), a wealthy widow recuperating from a broken hip, becomes trapped between floors in the cage-like elevator she has installed in her mansion. With her son, Malcolm (William Swan), away for a summer weekend, she relies on the elevator's emergency alarm to attract attention, but the only response comes from an alcoholic derelict, George (Jeff Corey), who enters the home, ignores her pleas and steals some small items.
