Machine Gun McCain (1969)

After serving 12 years behind bars for armed robbery, tough guy Hank McCain finds himself the pawn of a ruthless mob runt’s rebellion against a high level don. When McCain discovers that he’s been betrayed and abandoned by his new employer, he retaliates with a high stakes Las Vegas casino heist that erupts into all-out war on the streets of Los Angeles, San Francisco and New York. Not blood, nor lust, nor wedding vows can come between McCain and his money…or his machine gun.
