Sonny tells a national magazine that truckers are the toughest men in America, and lands in a Marine boot camp to prove it. They didn't have to twist Joe Frazier's arm to induce him to "act" in a TV show, especially when Joe and friend Ali were trying to publicize their rematch. The plot tonight has Sonny and Will being conned by fellow truckers Moose and Benjy into proving they're tougher than Marines. So, off they go to Camp Lejeune, N.C., for a week of training with real Marines and the climax: Will (Frank Converse) in the ring with Pacific Fleet champion Cpl. Brooks (Frazier).
