Mitch Mason, ex-manager of a once-successful rock'n'roll band, discovers the Twist being played and danced in a small mountain town. He books the band, led by Clay Cole, and dancers Tina and Larry for a Boston society benefit, and they create a sensation. But they're unable to get other bookings because Mitch has spurned the advances of Debbie Marshall, the daughter of New York's top agent. But a friend of Mitch's books them into a club where Chubby Checker and Dion are also appearing. They are a smash hit, and the Twist sweeps New York. When Debbie suspects that Mitch is falling in love with Tina, she gets her father to sign the group on the condition that Tina not marry for 3 years. The Twisters appear on a nationwide TV jamboree, and Mr. Marshall learns that Mitch and Tina were secretly married before signing the contracts.
