Sergio (Luis Tosar) has serious gambling problems. After swearing to his wife that he would not fall for it again, he receives a tip about an alleged soccer match fixing and, unable to keep his promise, he returns to the betting house with the intention of recovering all the money lost. The tip turns out to be true and his luck is finally going to change… but Alejo (Aron Piper), who also has a gambling past, bursts into the place with a gun.
Pablo (Alex Garcia), a GEO sniper, is pressured by Commissioner Costa (Elena Anaya) to serve in the heist. But the GEO’s head is elsewhere, in the hospital, where his son’s life hangs in the balance.
As fate would have it, Sergio and Pablo are involved in a robbery at a gambling house, where a gunshot will change their lives forever.
