La Frontera S01E04 - Dudas

Mario's informant discovers the identity of one of the dissident ETA members. Meanwhile, the captain and Izaskun risk their lives to obtain information from the Marseille mafia, who are about to sell explosives to the terrorists, believing them to be bank robbers. The only possible course of action is to allow the surrender, follow the ETA members, and dismantle the commando before they act.
