Argentina, 1965. Angel, a drifter, and Nene, a petty thief, meet in the bathroom of a Buenos Aires train station, and from that moment they are inseparable--both as lovers and, soon, as partners in crime. Dubbed "the Twins" by the police and tabloids, they scratch out a living trawling through the Buenos Aires underworld, until a botched heist goes wrong: leaving four dead and Angel wounded. It forces them and their swaggering straight cohort Cuervo to escape to Uruguay as per the orders of their boss, the sinister Fontana. Fugitives, they are advised to remain in hiding. until their false documents are ready. Days go by and tensions mount. The three begin going out and attracting attention. The situation worsens when Nene, who has an unhealthy relationship with Angel, falls in love with a prostitute. Cut off from their roots and the connections, convinced they've been betrayed and are under surveillance, the Twins' world begins to close in on them, testing their love and finally their sanity.
