A beach party rock and roll monster movie
Theodora, Jody and Carol, collectively The Violas, are on tour when their van breaks down in a small southern beach town. The local police are investigating a mass of mysterious debris on the beach and the disappearance of a little girl's parents after she's found walking the beach in a state of shock. Scientist John Patterson is called in to help investigate. Both John and local mechanic Hector Garcia fall for Violas lead singer Theodora, but she seems to have no interest in them, possibly because of a mysterious past. Hector convinces the girls to stay in town when he offers to repair their van in exchange for playing his party, but the mysterious creature is still on the loose.
