Castelar, "The man on the overcoat" and "The Red-haired one" are three petty criminals engaged in organized pick-pocketing in the Rastro (Madrid). One day they meet at the behest of his former partner Daniel "The Melancholy", which plans to commit a robbery at a jewelry store. The attempt turns out to be a resounding failure, but Daniel does not cease in its efforts and commends them shortly after the theft of the contents of the safe in a mansion. The problems are quick to reappear: the owner Mrs. Andrea died poisoned by Germana, her sister, and her husband Don Felipe, the owner, is being poisoned slowly in infusions, just as it was Andrea, and if that were not enough, Daniel falls for Herminia, goddaughter of the owner.
