An isolated mountain resort town is preparing for a massive influx of holiday swimmers. Just before the opening, a reckless skip tracer investigating a missing hiker accidentally releases a swarm of deadly, genetically engineered piranha into the river system. The lethal fish, bred for military purposes, now head straight for the crowded resort waters, and a race begins to warn the town before the piranha begin their feeding frenzy.
