Harvey is mistaken for a witch and is captured by the villainous Tim. Sabrina must save Harvey before he winds up being in Tim's clutches for the rest of his life.

Sabrina is psyched about the school dance and can't understand why Harvey doesn't want to go. She learns that Harvey can't dance, so in order to help him she summons the Lord of the Dance (Hilda's old boyfriend). The Lord produces a pair of shoes that makes Harvey a dancin' machine. Every time music is heard Harvey's feet do their stuff... and won't stop. Since the Lord is under no obligation to remove them Sabrina must get the shoes off Harvey before he dances himself to death.
