The pair of investigators Capitu Machado and Juca Pirama travels to Vila Antiga dos Astronomos to unravel the Crimes of the Tarot, ritual crimes based on the greatest arcana of the mystic deck. There, they are received by Chief Leonardo Pataca, who takes them to the first victim: the hanged man.
Juca, after being attacked by an enigmatic figure, returns to the inn, where he meets Capitu and her research partners, the heroes of the Mystic Parthenon: Vitória Acauã and Dr. Benignus. A second death is reported, inspired by the arcane Os Amantes.
Capitu and Benignus wake up in a shed in the presence of the assassin and his minions. The assassin, whose identity remains unknown, orders the heroes to be killed. At the other end of the village, Juca and Vitória investigate the third murder: two bodies found near the abandoned locomotive.
Amid other crimes, the group of heroes debate the case for clues and hold a techno conference with the Dread Dr. Louison. The history of the sect dedicated to Pamu the Venerable is revealed, as well as other crimes in the tarot. Will these heroes be able to discover the person responsible for the deaths, stop the villains and save the Old Town?
Benignus organizes the group's individual missions. Vitória and Juca are going to investigate the local police. Bento and Capitu go talk to Aurelia Camargo, because maybe she's hiding more than she knows. As for Sérgio, in the company of Father Eugênio Guimarães, he goes to visit the shed where an entire family was killed.
Bento pressures Aurelia to reveal what he knows, but Capitu stops him. He talks to her and, through dialogue, tries to dissuade the woman from a possible escape. Vitória and Juca try to escape from prison. Meanwhile, the enigmatic villain and Nioko Takeda recount their plan and set the stage for their ultimate sacrifice: now recreating the Death card. Around them, the worshipers of Pamu appear.
Now, occult investigators and the minions of the tentacular creature Pamu are gathered for the ultimate clash! Who will survive? Old Village - and the rest of the world - can they be saved from the monstrous domain of Pamu?
In prison, Guimarães has a final dialogue with police chief Pataca and his first officer, Crispim. Juca and Vitória say goodbye at the cemetery, promising to meet soon. Capitu talks to Benignus about her past and Takeda's future, after receiving an important message from the past. Sergio and Bento plan the next adventure.
