Prom Night has arrived, and a radiant DJ (Candace Cameron) enters the school auditorium with her date Steve (Scott Weinger) by her side. Unfortunately, Steve has been elected Prom King, meaning that he will have to spend most of the evening with the Queen, his former girlfriend Rachel (Cristi Harris)--and even worse, DJ and Rachel are wearing identical dresses. Saving the evening from total disaster is Uncle Jesse (John Stamos), who is in charge of the dance music. Meanwhile, Danny (Bob Saget) finds out that Vicky (Gail Edwards) has been keeping a "chronological" secret from him. ~ Hal Erickson, All Movie Guide
