‘Go fuck yourself in the ass’ (Vai tomar nu cu). What does this common Portuguese insult mean to those who have anal sex? Who has the power to decide which body parts are considered sexual? Can we see through ‘the eye of the anus’ (literally)? These are questions that permeate this film, which invites viewers to plunge into the protagonist’s memories, despair, and desires. The asshole initiates the film and functions as a gateway into the character’s mind.
