Piranha

The private investigator Maggie McNamara (Alexandra Paul) from Lyon Investigation is hired by the wealthy J.R. Randolph (Monte Markham) to find his niece that has disappeared with her boyfriend. Maggie seeks out the lonely environmentalist Paul Grogan (William Katt) to help her to look for the teenager. They head to an abandoned army facility and Maggie decides to drain the pools to see whether the body of the girl is there. They are assaulted by a woman with a crowbar but they subdue her. However she escapes and soon they learn that the woman is Dr. Leticia Baines (Darleen Carr), who is researching a hybrid species of piranha that is capable to survive in fresh and sea waters for military purpose. Further, Maggie has release the piranhas on the river and they are heading to the Lost River Lake Resort. Maggie and Paul inform the corrupt local Sheriff but Randolph tells him to lock them up since he does not want to jeopardize the party he has promoted to his resort.

"Piranha" is a B-movie with the same storyline of "Jaws". There are ridiculous scenes, like for example, Maggie tasting the water of an abandoned experimental pool. Or the heroine Maggie opens the drain valves without measuring the consequences and causing the death of several people. Or when Dr. Baines dies and Maggie and Paul say that they need to find someone with knowledge in piranhas. Or the instructors of the children camping that do not use the boats to rescue the children, walking on the water under attack of piranhas. It is funny to see Maggie driving the high-speed motor boat at full speed pulling Paul tied to a rope. My vote is three.
