After breaking up with Viper (David Lipper), DJ (Candace Cameron) reconciles with her wealthy former beau Nelson (Jason Marsden). But before long, she finds herself in the middle of a muddle when Viper comes back into her life, forcing her to choose between the two boys--immediately. Meanwhile, the rest of the Tanner household pitches in to help clean up a vandalized community playground, resulting in a sticky situation for Joey (David Coulier). Singer Frankie Valli appears as himself. ~ Hal Erickson, Rovi
