Several sexual encounters show nudity and sometimes rather explicit movement, and masturbation is implied in one scene. There are also varying degrees of bad attitudes and behavior displayed by the young men. They treat women pretty much as sexual conquests to be had, and Sonny doesn't believe in God. The young men also do their fare share of drinking and smoking. We see beer and whisky ads early in the film.
People drink in the background of several scenes.
Gunner drinks beer on a train, and later he and Sonny drink Saki. The guys drink beer in a bar and in other locations several times. Nina pours herself a drink and the guys have beer. We twice see Gunner drinking and driving. Sonny's face is black and blue after a car accident.
