Eddie and the Cruisers, a major rock 'n' roll band in the early '60s, fell off the radar when singer Eddie (Michael Paré) vanished after a dispute over their experimental second album. Nearly 20 years later, journalist Maggie Foley (Ellen Barkin) tracks down the old Cruisers to see if she can unravel the secret of Eddie's disappearance. By piecing together the band members' stories, she hopes to find the missing master tapes to the lost LP, and also solve the mystery of Eddie's ultimate fate.
