Martín, a former militant who has been in exile in Spain for more than thirty years, receives a call from an old comrade, Raúl, asking him to return. The aim is to help him with the excavation work that Raúl has begun in the jungle, in which he is trying to find the remains of a mutual friend, Ezequiel, who disappeared after a skirmish with the military. The excavation organised by Raúl is clandestine, carried out behind the government's back, so that he can do things 'his way'.
