With Pete Smith providing dry off-screen commentary, we watch some serious fishing: a marlin caught near Catalina, a hammerhead shark caught then wrestled in a small rowboat near Baja, the largest (721 pounds) great white shark caught to date in California waters, Chinook Indians catching salmon at Celilo Falls in Oregon - each with his designated place on the river where his ancestors stood, and, last, a crew on a boat off Mexico hoisting and hurling tuna using unbarbed hooks (baited only with a feather) as fast as they can as long as the school is there - backbreaking work - but a $25,000 catch.
