Two years after consorting with the wrong people cost him his job as public prosecutor, Eduardo Silva is a measly defense attorney, who works from his hotel room. Loosing a bit from her fellow-angler uncle, he gives a shot as unpaid apprentice to freshly-graduated gypsy Marcia Amaya, whom nobody would consider hiring so far, but is soon offered crossing to the office of Silva's successor as prosecutor. Their first client is common-as-muck Joana Soares, accused of murdering her beached-up husband after a public fight, without an alibi, claiming a blackout. Eduardo is countered while working out, with help from Marcia's and Joana's families, how the affair actually relates to illegal trade in medicine, with twists including the involvement of a crime lord.

Lisbon Attorney and former DA Eduardo Silva never got over the death, two years ago, of his wife valentine in a car crash. When he and his gypsy assistant Marcia Amaya hear crime baron Tiago Zarco is arrested having been found over the corpse of the massive pharmaceutical fraud case, she's surprised like the DA that Eduardo offers to defend Zarco, who accepts while keeping his uncooperative right hand-lawyer on, even if that solves their law firm's dire financial state. Silva seems prepared to risk his lawyer license for vengeance on the monster who had an affair with Valentina, yet refuses to look away from indications that Zarco hasn't committed or ordered the murder, but sets a risky trap for those fiends, which proves extremely difficult and dangerous.

A snowed-in holiday hotel. A dead body in a room locked from the inside. The hotel manager wants to cover it up, but in the blink of an eye the whole hotel knows about it. Among the guests is an inspector - or at least he convincingly claims to be - who, together with his assistant who has travelled with him, undertakes extensive investigations. Then even a second murder takes place!
