The family's Halloween celebration takes a sinister turn as Juan, the step-dad, reveals his true intentions. He's invited a mysterious guest, a high priest of some dark cult, who demands a virgin sacrifice. Asteria, the step-daughter, is the chosen one. Anna, the step-mom, and Cherry, the half-sister, are forced to watch, their roles as reluctant spectators and unwilling participants in this fucked-up family tradition. Asteria, in her white dress, is stripped naked, her innocence a stark contrast to the dark ritual about to unfold. The priest, his eyes gleaming with lust and malice, approaches her, his intention clear: to claim her virginity in the most taboo and depraved way possible.
