It's Saint's Week in Seville when detective Maria Delgado hits town. She's running from the past, her new partner doesn't like her,
and she's just in time to investigate a bizarre double murder.
As Maria joins forces with the shy Torillo and the resentful Quemada, a third brutal death points to the presence of a serial killer. At first there are no clues, but when an old woman tells Maria about a terrifying place called La Soledad, the truth begins to emerge...
The three detectives begin a cat-and-mouse chase with an insane but ingenious killer, and at the same time they start to uncover a history that somebody wants very badly to conceal. As the trail gets clearer,
it becomes a great deal more dangerous. One thing is certain: more blood will be spilled before the end of Semana Santa.
