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. Neither blood, nor lust, nor wedding vows can come between McCain and his money ... or his machine gun.
Unfortunately the movie Machine Gun McCain is not yet available on HBO Max.
