Hermano, a successful doctor and enthusiastic rock climber, is planning to climb an almost invincible mountain in the Tierra del Fuego, when he discovers that his wife Adri is pregnant. Though Adri desires this unexpected pregnancy, Hermano is a bit reluctant to be a father, and he is obsessed by the challenge of the mountain. For Hermano, facing the mountain represents an essential proof of courage that he believes he owes to himself. Despite discovering that Adri's pregnancy is at risk, he seems determined to go ahead with the climb. Stricken by guilt since adolescence for having done nothing to save his friend Bonobo from a brutal beating, which resulted in his death, Hermano now thinks he can only redeem himself with this heroic act. On the day of his departure, Hermano relives the tragic event that has indelibly marked his life, just as Adri is rushed to hospital in premature labour, with all the more serious risks that this entails. What are Hermano's moral and personal options?
