A guard is seen accepting money of the two inmates at night and he hands them a key implying that they bribed him to set them free.

A father takes nude pictures of his daughter and her male friend. Child molestation is strongly implied, not shown, but aftermath is discussed by victims years later.

Evan consistently throughout the movie has nose bleeds, in which he starts shaking rapidly and violently or goes into shock, alternate timelines are shown throughout each nose bleed.

A child kills another child's dog by burning it in a bag (animal cruelty). The actual burning isn't seen, but the aftermath is shown.

The movie is very traumatic and not for kids as it is rated R for a reason. It gets more and more disturbing as the film progresses

This is a very depressing movie.

Themes of child abuse, pedophilia, bullying, and people going insane.

All the main characters are messed up in one way or another: one is a sociopathic sadist as well as a victim of child abuse, one is a victim of psychical and sexual child abuse, one is very unstable and overrun with guilt, one doesn't know if he is crazy or has God like powers, one is depressed that she is unable to have a child, one is a pedophile, etc.
