Max Goof is an average teenager who pines after his classmate Roxanne, idolizes the pop star Powerline, and has a tense relationship with his clumsy, old-fashioned father
Goofy, whom he fears he may end up taking after when he grows up, having already inherited his laugh. On the last day of school before
summer vacation, Max, with help from his friends
P.J. and Bobby, hijacks a school assembly and dances while
lip syncing to a Powerline song. The performance succeeds in making Max a school celebrity, and he invites Roxanne with him to a viewing party of a live broadcast of Powerline's upcoming concert in
Los Angeles. Goofy, after school principal Mazur warns him about Max's potential
juvenile delinquency, immediately plans a fishing trip to Lake Destiny,
Idaho, to curb his son's behavior. Max attempts to cancel his date with Roxanne, but panics and tells her that not only are he and Goofy traveling to
Los Angeles to attend the concert, but that Powerline has invited them onstage. Goofy and Max hit the road, visiting a run-down
possum-themed
amusement park where Goofy embarrasses Max. The next day, they run into P.J. and his father,
Pete, while camping. Goofy takes his son fishing and shows him the "Perfect Cast" fishing technique, accidentally luring
Bigfoot to their camp and forcing Goofy and Max to spend the night in the car with Bigfoot outside. While Goofy sleeps, Max alters the map's route to Los Angeles. The next morning, Goofy makes Max the navigator of the trip, and the two enjoy several stops together. That night, while staying at the same motel, Pete overhears a conversation between Max and P.J. and informs Goofy that Max has tricked him into traveling to Los Angeles. Goofy still believes Max will do the right thing, but the next morning, Max chooses the route to
California, and Goofy stops the car at the
Grand Canyon and storms off. With the brake loose, the car drives off on its own; Goofy and Max chase after it and end up riding the car down the
Colorado River. After a brief argument, Goofy says no matter how old Max gets he will always be his son, and the two finally reconcile. After learning about Max's promise to Roxanne, Goofy decides to take him to the concert. The two nearly plummet down a waterfall, but Max rescues Goofy using the Perfect Cast technique. In Los Angeles, Goofy and Max arrive at the concert, sneak on to the stage, and dance with Powerline, delighting Roxanne. Max and Goofy return home in their barely functioning car and Max tells Roxanne the truth; she admits she always liked him and they make plans to go out. The car explodes, ejecting Goofy into the porch roof of Roxanne's house, and Max proudly introduces his father to his new girlfriend. ==Voice cast==
