The film contains some scenes of violence.
In one of the scenes, Oscar hallucinates that he is pulling out an iron rod that is protruding from his abdomen.
In another sequence, a group of boys is seen attacking another boy with an iron rod. There is a close-up shot of the iron rod being twisted, suggesting that it is being used to inflict pain on the victim. The focus, however, is on the rod with no depiction of the victim's reaction. In a later scene, the rod is seen lying next to the victim's dead body, with blood stains on it.
While strongly suggestive, the scenes are presented briefly and do not portray any detailed infliction of pain or injuries.
