Radioactive waste dumped off the coastline creates mutant monsters. The beasts attack slumber parties, beaches, tourists, and terrorize a waterfront community as a scientist, his daughter, her boyfriend and the local police try to find a way to stop them.
Unfortunately the movie The Horror of Party Beach is not yet available on HBO Max.
