Jaime Guzmán, the main ideologist of the Pinochet dictatorship and author of the Chilean Constitution, slips into a witch's dream. She confronts her different personifications and tries to drive away her visitor using witchcraft. She curses, sings, dances and reintroduces herself in alternative versions of herself.
Commissioner Leon (Miguel Angel Landa) investigates the murder of a woman in a population near the capital. The woman was raped before death and the case is complicated when his brother becomes the prime suspect, since it is a priest (Eduardo Serrano). Because of the implications that inquiries might have, Leon is pressured to keep the event as a "crab" (Cangrejo, or a unsolvable case), but he decides to comply with the law.
