Piranha II: The Spawning

Piranha II: The Spawning, also known as The Spawning and Piranha II: Flying Killers, is a 1981 American horror film, the sequel to the 1978 low-budget cult film Piranha, directed by James Cameron in his theatrical feature film directorial debut.

Plot

Shortly after the conclusion of the first film, the piranhas from the military camp have infact reached the ocean, and have somehow mutated into winged creatures. Meanwhile, off the coast of a Caribbean island, a young couple flee a hotel to have sex in the sea. But they swim into a sunken wreck which is also a piranha lair and they are both killed and eaten by the unseen piranha.

The next day, a group of tourists, including Tyler Sherman, are taking the diving courses provided by Anne Kimbrough, an employee of the Hotel Elysium. One of her divers swims into the wreck, which she has strictly forbidden to her divers. Leaving Tyler to take over and lead the others to the surface, she discovers almost immediately that her 'missing' student has swum into the wreck and been killed there when his badly chewed up body is found.
