Bobby James (Jim Bray) and his friends (Phones, Hoppy, Gordo, and several others) skate to work on the boardwalk in Venice, California. Meanwhile in Beverly Hills, Terry Barkley (Linda Blair), a genius flautist is also heading towards the beach in her Excalibur Phateon automobile. She also is joined by her snobbish girlfriend Lana (Kimberly Beck).Bobby is skating on the boardwalk with a female friend when he encounters Terry. But she remains aloof and spurns his advances. They later meet at a local skating rink called Jammer's. During a near catastrophic incident where Bobby saves the day, she gives in. Terry wants to pay him to teach her how to skate for the Roller Disco contest. Even though they share a flirty, romantic couples skate, later on she rebuffs him yet again.The next day has both Terry and Bobby getting flack from their respected friends and family. She has had enough and goes to the beach. She finds Bobby there, practices a jump and turns on the charm. He shares with her his dream of becoming an Olympic Roller Skater. They end up making out on the beach. Bobby asks her if she's going to pay for him for sex as well, which garners a mighty slap in return and takes off.Terry goes home and has a row with her mother (Beverly Garland). She wants to give up her dreams of playing Classical Flute at Julliard School and win a roller disco contest at the beach. Her mother is shocked, enough so she needs a Valium. Terry decided to run away. The next morning, she calls and invites Bobby to breakfast where she apologizes. He wants to skate with her, but on his terms: on money; he calls the shots. Through a series of outdoor scenes, we see them work together to form a routine.Unfortunately, Jammer's is about to be sole 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 her hanging out with her radical friends. The skaters find evidence, in the form of a 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 this to the police on time. They do, the mobsters are hauled up and the Boogie Contest is on. Terry and Bobby skate their routine and win the contest.Later on back at the beach, Terry and Bobby share an unhappy goodbye. Both promise to write each other as she heads off to New York City and he heads off to the Olympics.
