Unfortunately, Jammers is about to be sold to a ruthless mob developer. Bobby and Terry are clued into this plot and try to get her father, a lawyer, to help. But he refuses. While Terry is performing at a lush outdoor party, some of the young men sneak up, causing chaos. As a result, a group of distinguished guests falls into the swimming pool. This ruins the concert, as well as the party and its ceremonial cake. Terry gets reprimanded and slapped by her father for her running away, as well as for hanging out with her radical friends. The skaters find evidence, in the form of a cassette tape recording of the invalid ordeal, to kill the deal. Through a wild chase on the streets near the canal zone of Venice, they race to get it to the cops on time. They do, the mobsters are hauled off and the Boogie Contest is on. Terry and Bobby skate their routine and win.
