Atomic Shark

American horror in which beach-goers on the coast of San Diego are in for a shock when a deadly shark begins to wreak havoc in the waters. When the locals first become aware of an unidentified threat in ocean, they are alarmed to hear rumours of a Russian submarine nearby. However, their worst fears are nowhere near as horrifying as the truth - that a gigantic shark with nuclear energy is approaching the coastline, and can't wait to get its jaws around anything that gets in its way.
