A prowler has been spotted in the building. Alice is so scared that she can't sleep, so she makes Ralph stay up with her and barricade the door. Norton comes banging on the door and scares them. Trixie comes down to get Norton. Next thing you know, the prowler climbs in through the Kramden's window and hits Ralph on the head. Ralph gets knocked out and Alice screams. The police hear the screams and come in and arrest the prowler. Ralph recovers and tells Alice that as long as he's around, she has nothing to worry about. Running time: 11:03 (thetvdb.com)
