A crusty recluse (Franco Nero) on a Caribbean island, who is dedicated to destroying sharks, gets involved in a race with the mob to find a buried treasure. Also stars Werner Pochath and Jorge Luke. Also with Michael Forest and Patricia Rivera.
Revealing mistakes: Despite supposedly being alone and five miles off shore, a boat can clearly be seen passing behind the actors at one point. Interesting to note, that same problem was one of the main concerns director Steven Spielberg had to deal with during the filming of Jaws (1975).
