After the events at Lake Victoria, the prehistoric school of blood-thirsty piranhas make their way into swimming pools, plumbing, and a newly opened water park.
This movie contains 14 potentially triggering events.
About 16min into the movie you see a number of dead creatures inside glass jars. Most are not identifiable, but there are fetus: ducks, pigs; and other underwater life (including an adult piranha) dead in the jars.
