When his sister Amy (Lily Nicksey) advises him to try the "polite" approach with girls, Cory (Ben Savage) begins dating a young lady named T.K. (Danielle Harris). Soon after, and much to his surprise, Cory is being treated with utmost courtesy by none other than school bully Harley Keiner (Danny McNulty). What our boy doesn't know is that T.K. is actually Harley's sister--a fact that may result in horrific consequences when Harley wrongly believes that Cory is "moving too fast" with the girl! ~ Hal Erickson, Rovi
