Several people have decided to go swimming at the swimming pool at Coney Island. They include a young woman with a strong armed boyfriend, and another young woman accompanied to the park by her overprotective parents. Complications begin when the second young woman begins cavorting with the assistant lifeguard, of who her father does not approve. In trying to get the assistant lifeguard to leave his daughter alone, the father inadvertently gets involved with the second young woman, which brings her strong armed boyfriend into the picture.
