The gang share a strange Halloween, complete with comic spoofs of several Alfred Hitchcock movies. Eric has vertigo after falling off the garage roof, Fez and Hyde spy on the Pinciottis, thinking Bob killed Midge, while Donna wants to prove to Eric that she's not boring. Meanwhile, Kitty and Laurie have a hard time feeding a neighbor's birds and a paperboy whom Red forgot to pay mistakes Kelso for someone in the Forman family and stalks him.

Donna suspects Eric is cheating on her after finding a pair of panties in his car, but its owner turns out to be someone she knows. Kitty is concerned with Red's high blood pressure and puts him on a less than satisfactory diet.
