Summary
A skip tracer searching for two missing teenagers teams up with a reclusive scientist after she inadvertently drains a pool containing genetically engineered piranha into a Texas river. As the swarm heads downstream toward a children's summer camp and a new riverside resort, the pair race to warn authorities who refuse to believe the threat.
