The movie is about stopping a deranged killer that is on the loose. As such, there are quite a few scenes where people are chopped with a cleaver and the resulting aftermath of blood everywhere.

A guy's throat is slit (again, only aftermath is shown).

A girl stabs a guy in the chest.

A girl is stabbed in the chest while on the toilet.

A guy is stabbed through the back.

Quite a bit of profanity. They use "fuck" and "shit" a lot in many variations.

The girls call each other "whores" and "sluts" and "cunts" quite a bit.

The main characters throw a party where there is a lot of drinking.
