Seven Beauties by Wertmueller 1975

Pasqualino is a small business owner in Italy and he believes in honor. After accidentally killing a man (in the name of honor) and cutting him up and packing him in a suitcase, and then getting caught, he goes into the Italian army, deserts and the Nazis send him to a death camp.

But Pasqualino was blessed with the seven beauties and when he finds the Commandant of the camp is a woman – a morbidly obese and disgustingly ugly German lady – he realizes his only recourse to survival involves sexually seducing her.

Others in the camp with courage and integrity and compassion die in the most disgusting manner – one man commits suicide by jumping into a trough of human shit. Pasqualino survives. Well, Pasqualino always survives and you are surrounded by Pasqualinos and may not even know it.
