In the sixties, Eddie and the Cruisers were the hottest band around. But the tragic death of its lead singer broke the band up...only Eddie is not dead. He works as a carpenter in Montreal, but his love of music forces him to create a new band which will have to struggle with its anonymity.

Tripper is the head counselor at a budget summer camp called Camp Northstar. In truth, he's young at heart and only marginally more mature than the campers themselves. Tripper befriends Rudy, a loner camper who has trouble fitting in. As Tripper inspires his young charges to defeat rival Camp Mohawk in the annual Olympiad competition, Rudy plays matchmaker between Tripper and Roxanne, a female counselor at Northstar.
