The Getaway (1972)

Four years into his ten-year sentence for armed robbery, Carter “Doc” McCoy is denied parole from a Texas prison. When his wife Carol visits him, he tells her to do whatever is necessary to make a deal with Jack Beynon, a corrupt businessman in San Antonio, to free him. Beynon uses his influence and obtains Doc’s parole on the condition that he take part in a bank robbery with two of his henchmen, Rudy and Frank. Frank kills a guard, then Rudy attempts a double-cross, killing Frank and drawing on Doc, who quickly reacts and shoots Rudy several times. Doc takes the $500,000 ($3,220,035 in 2021) and leaves. Rudy, having secretly worn a bulletproof vest, is only wounded.

Doc meets with Beynon, not realizing he had arranged a double-cross wherein Carol would sneak into the meet and kill Doc; however, Carol turns her gun on Beynon, killing him. Doc, having just been taunted by Beynon before Carol shot him, realizes that Carol had sex with Beynon to secure his parole. He angrily gathers up the money and, after a bitter quarrel, the couple flees for the border at El Paso.
