In a Gothic-styled monastery, a monk named Javier sees the face of another monk, Juan, and suddenly attempts to bludgeon him to death with a heavy crucifix. Both men then relate their own versions of a story of romantic rivalry between them. Javier, a consumptive musician, fell in love with and was betrothed to Anita. When his old friend Juan appeared, he was ecstatic. But soon, it seemed that Juan was making a play for Anita. When Javier found them in an apparently compromising position, a tussle ensued, and Anita was accidentally shot and killed. The two versions of the story differ significantly in Juan's motivations and in the details of Anita's death. Both men later became monks, leading to their latest encounter. As Juan begins to recover from the blow, Javier is subjected to horrific hallucinations.—goblinhairedguy
When the Monk Javier acts violently in a gothic monastery, the Prior asks the Monk Juan to calm him down since he believes that Javier is possessed by demons. When Juan comes to Javier's cell, they recognize each other and Javier runs after him. Javier reaches Juan and hits his head with a heavy crucifix, and returns to his cell. Later, Javier confesses to the Prior that Juan was his best friend when he was a tubercular musician and how their friendship ended when his beloved fiancé Ana died. Then, Juan confesses to the Prior that Javier's confession is correct, but he would like to tell the same story through his eyes.
