Killer Fish is 1979 suspense/horror film directed by Antonio Margheritti.
In Brazil, a team of thieves steals a cache of valuable jewels and hides them at the bottom of a reservoir until they be retrieved without attracting the attention of the authorities. Unbeknownst to the thieves, the mastermind of the theft has stocked the reservoir with deadly piranha in order to prevent any of the team from betraying him by retrieving the stolen gems without him.
