The girls of Alpha Beta need to raise $10,000 in two weeks to save the sorority house. Among their schemes to raise the funds are a beauty contest, a newspaper puzzle, and a baking contest. But when three guys hit the beach with love on their minds, bragging that they know the Beatles, the girls plan a concert with the Fab Four as the main attraction.

A young girl is killed at the beach in Malibu. Professor Otto Lindsay suspects that it is some form of mutated fish. However, his son Richard, who was a good friend of the girl, thinks that it is a madman who has a grudge against Richard and his friends. Soon the list of victims grows.
