On 17 April 1928, seven inmates from the National Penitentiary in Buenos Aires manage to escape by tunneling their way out of prison: Laureano Irala, an ex-con, Domingo 'El Pibe' Santalón, an expert poker player and forger, Julio 'El Profesor' Bordiola, a bookmaker, Tomás Opitti, an airplane pilot, Belisário 'El Pampa' Zacarías and Omar 'El Turco' Zajur, both kidnappers and murderers, and Camillo Vallejo, an anarchist.

Soon after the event, Police commissioner Duval begins investigating the case as the men part ways: Vallejo attempts to bomb a government coach, but is killed when the explosive fails to detonate at the right time; Zajur reunites with El Pampa's widow, La Varela, and it is revealed they were on a relationship; Santaló seeks his former boss, gambler Pedro Escofet, in order to resume his gambling ways and to reunite with Escofet's wife Tabita, with whom he has an affair; Irala returns to the coal store out of guilt for the old lady's death, but the old man mistakes him for his nephew who lives in Mendoza and asks him to move in; and Tomás escapes in a biplane to an aero club in Entre Rios.

In a series of flashbacks, it is revealed that Tomás flew a terrorist and was mistaken as his accomplice, which prompted Duval and his men to shoot and kill his wife and son and arrest him, even though acknowledging his innocence.

In the present time, upon landing in Entre Ríos, Tomás witness his fellow co-pilot being gunned down by Duval and his men in an ambush set to kill him.
