When flesh-eating piranhas are accidentally released into a summer resort's rivers, the guests become their next meal.
When the guard at the dam is watching a commercial promoting the resort at Lost River Lake, originally some of Dumont's campers were part of the promotion, but this was cut from the movie. Another scene cut was Dumont accidentally appeared in the background of the commercial, ruining the shot. He was ordered off the premises by Buck Gardener.
Terror, horror, death. Film at eleven.
As Dr. Hoak is attacked by a piranha, he gets onto a raft and his sweater alternates between torn and intact.
The title sinks into the pond water at the start, and turns it blood red. Over the end credits, we hear the sound of piranhas swimming in the ocean. The water turns red as well.
