Santiago del Estero, Argentina. Nino lives with his family and he is in the midst of exploring his early awakening sexuality. At fourteen, Nino is already a victim of homophobic attacks. To protect him, his parents decide to leave the city temporarily and the whole family moves to the forest exploitation where his father works.

The farm is surrounded by the monte, a huge humid and dark forest. Nino feels guilty for what he is going through and for having turned his family's life upside down. His sister Natalia, aged 16, far from her friends and in her teens, does not spare him. Estela, his mother, wants to put Nino back on the right track and organizes his Confirmation in the local church.

In this rural and superstitious environment, Nino hears about a mysterious creature called the Almamula, which takes with her anyone who has committed sexually reprehensible acts. The Priest's sermons show Nino that his sexuality is not seen well before the eyes of God. The pressure of the approaching ceremony weighs on him and his fascination for the Almamula, who would accept his sins, grows. Little by little, Nino joins the Almamula to his prayers seeing in it as his salvation, and going in search for it.
