Gregorio Gamboa is back in Uruguay after leaving years before because of political problems. He returns with his wife, Mercedes, an argentinean he met in Spain, and his two adolescent children, Mateo and Cayetana, born in the same country and forced into a land they know only throught the biased tales of their parents. Together, they plan to build their definite house over land that belonged to Gregorio's grandfather, but little does the rest of the family suspect that beneath the terrain there is a huge number of weapons buried by Gregorio during his youth. One day, in a moment of reconciling, the father tells Mateo his secret, unleashing a wave of events that will change their lives forever.
