Héctor Alterio stars as José, an aging anarchist who decides to get even with the bank corporation that stole $15,344 from his family eighteen years earlier. He plans a defiant move, but when confronted by the yuppie manager, Leonardo Sbaraglia as Pedro Mendoza, José threatens to kill himself and demands that the money be handed over. In the ensuing chaos, Pedro stumbles upon a drawer holding half a million dollars and stuffs it into a bag. He then asks José to take him hostage so the police won’t shoot them, and the two men manage to drive away with the cash.
After the robbery, Pedro discovers the funds are laundered money that Pedro’s boss Rodolfo has kept for the mafia with bank knowledge, which would put him in trouble with both groups if he turns himself in. After learning this, Pedro joins José on a road trip to Patagonia as they flee from police and hired thugs. On the road they bond and decide to challenge the false claims made by the media about them, taping a message and sending it to the TV. They become the subject of press coverage as modern-day Robin Hoods, nicknamed Los Indomables by the public.
The duo decide to take a bus that will bring them closer to the border with Chile, and aboard they meet Ana, Cecilia Dopazo, a punk girl who initially steals the bag containing the half-million but returns it when they catch up. They decide to let her into their circle, and she even helps by stealing a jeep for them. The three soon devise a plan to "return" the money to the people by creating a mock-up bomb that blows up a briefcase containing the half-million, which rains down on a cheering crowd. Keeping only what is necessary for the journey, they set off again.
The group edges toward the border after dodging a pursuing helicopter, aided by gas station attendants who help them dodge roadblocks and two hitmen sent by the mafia, whom they finally overcome after swapping clothes and guns. Along the way they meet Eusebio, Federico Luppi who is married to Natalia, sister of José’s late wife Clara, and they reconcile the past. After this, José reveals his long-hidden past as a horse breeder, explaining he once fought to reclaim the land where his horses live before a meatpacking plant could seize them. He decides not to reclaim the land for himself but to buy all the animals so they can roam wild at the foot of the mountains.
As pursuers close in, José bids farewell to Pedro and Ana, who have fallen in love, and the three ride away on two horses toward the Chilean border. José then frees all of his horses, and as the last one is sent free, he is shot in the back offscreen. He dies with a sense of renewal—joy for life and for noble people restored—while his horses run free. A flashback shows José dancing to Tales from the Vienna Woods, celebrating the vitality he has found again.
