All of Me (1934)

In this melodrama, an engineering professor longs to leave his ivory tower so he can be involved in a special project taking place near Boulder Dam. He decides to go and tries to convince his wealthy student/lover to go with him. They discuss this in a night club. She doesn't really want to go. While there, they encounter another couple, a crook and his moll who offer their own unique take on the situation. The crooks offer the wealthy lovers insight into the realities of living on the lower rungs of the social ladder. At the end of the evening, the crook steals the wealthy girl's purse so he can help his pregnant girl. He gets arrested. Fortunately, the kindly professor helps him break out so he can be with his moll who needs him. Unfortunately, during the escape, the crook kills a cop and takes the professor and his girl hostage. The police surround the joint and the rich girl hides in a corner during a shoot out. The situation gets desperate and the crook and his lover vow that they will never again be parted and hand in hand leap from the window to certain death. The girl suddenly realizes the true meaning of love and decides to accompany her lover out west and start all over again. ~ Sandra Brennan, Rovi
