Christopher George is Chubasco, a hot-blooded son of a son of a fisherman who takes a sock at a cop and gets a choice: jail, or a job on a fishing trawler. There, he turns out to be a good man, with a pair of eyes that can spot the porpoises that betoken tuna, but bad luck for those around him; one of his skippers drops dead and when he ships unknowingly with the father of Susan Strasberg, with whom he has eloped, sparks fly.
Mostly, it's an okay coming-of-age story with some old Hollywood hands to keep fans of old movies like me happy: Richard Egan, Audrey Totter, Preston Foster and Ann Southern all have good roles, and Paul Ivano offers some good documentary-style footage the first time we see the nets released. On the down side, William Lava, the bane of all cartoon lovers (no fault of his, really; he just had no budget) offers a syrupy and overwrought score that has aged very poorly.
