The All-American Boy(1973)

Vic "Bomber" Bealer is a handsome, manipulative boxer who aspires to something greater than the small-town life he knows in Texas. But, even when opportunities present themselves, Bealer is too restless and indecisive to take advantage. Despite being on the cusp of making the Olympic boxing team, his life is in total disarray as he juggles relationships with an old flame, a girl who's way too young for him, and a foul-mouthed trainer.
