You see a girl showering in the background of a locker room (rear nudity).

Two boys shower together and kiss each other on the lips.

A guy kisses his girlfriend. The girlfriend acknowledges that her upcoming "appointment" might have something to do with their recent camping trip.

A teenage boy corners a teenage couple in a meat locker. He plays "eeny meeny miny moe" to decide which one to kill. We hear the couple begging for mercy.

A girl is shot in the face, with blood splattering behind her (but there's no entry wound).

A teenage boy is shot in the chest when he steps out of the classroom. The teacher drags him back into the classroom leaving a bloody trail. A man is shot three times, and he slumps down. Two boys are shot in the chest.

Several other teens are gunned down (seen from a distance). We see several corpses as the camera glides across rooms and down hallways.

There are little sounds heard other than gunshots when people are shot, however.

A boy plays a video game in which the objective is to shoot people in the back.

A boy says his parents are being retarded as an insult (same scene shown a couple times from different points of view)

13 fucks, 6 shits, and 4 bitches. Also 4 instances of "hell" and "God".

Smoking: a couple students smoke on the field.

Two student workers sneak into the cafeteria cooler and smoke what looks like pot.

One student's father is drunk while driving him to school. He swerves all over the road and sideswipes a car. We are later told the father is an alcoholic.

The shooting sequence is extremely disturbing.

Three teenage girls are bulimic, and can be heard vomiting in the bathroom.

The scenes of minor bullying can still be somewhat intense due to its realism.
