Much of the movie relies on iffy behavior with few consequences, but one character must decide between committing murder to protect his own safety and protecting his best friend instead; he chooses loyalty and friendship. The movie also deals with the idea of "consequences" for some bullies who've mistreated a woman, though it translates into simple revenge.
The violence doesn't really pick up until about halfway through the movie, after that there's plenty of it, including punching and fighting, shooting, and blood. A man is smashed in the crotch, and the movie climaxes with a bullet-ridden shootout. A main character dies. There are also heavy threats and suggestions of violence in the dialogue. A doctor plunges a hypodermic needle into a character's penis (off screen) after that character takes too much Viagra.
The main characters visit a brothel. One takes extra amounts of Viagra (only referred to as "boner pills") and sleeps with a prostitute off screen. A second character sleeps with two women at once, a prostitute and the woman at the front desk, both off screen (and without Viagra). A naked woman is found in a car trunk, but she's filmed curled up so that nothing is shown. Also very strong innuendo throughout, such as when a main character tries to pick up three women in a bar.
Very strong language includes many uses of "f--k," plus "s--t," "whore," "ass," "a--hole," "d--k," "boner," "damn," "goddamn," "oh my God," and "pecker."
Viagra plays a big role in the movie, though it's not mentioned by name specifically.
Drinking, Drugs & Smoking
Characters stay up all night and drink a lot of alcohol. They also break into a pharmacy and steal several bottles of prescription pills (mostly for things like cataracts and hypertension). One character breaks open some of these pills and snorts them. A main character is seen smoking cigarettes on more than one occasion.
