Tuna Clipper [1949] [DVD]

Because he's in debt, blue collar kid McDowall wants to go into the local tuna business, something his mother strongly objects to because of what happened to her older two sons. His parents hope he'll find a more white collar profession, but McDowall persists, and is soon flinging his pole out into the sea to bring in these surprisingly large fish that end up in small cans. McDowall finds initial resentment by the feisty Elena Verdugo, but she quickly comes to see his good nature behind the breeding his parents instilled in him to manipulate his future. There's also young Dickie Moore as his best friend and Roland Winters as the ruthless businessman who takes advantage of McDowall's naivete. Thanks to the support of his friends, fellow crew and the pretty Verdugo, McDowall's obviously going to make it even with all the bumps in the road. Nice location footage (looking like it might have been shot in an actual fishing community) is a plus.
