1986 Thomas is born with his eyes closed, and he does not open them for several weeks following the birth. Julieta, his mother, is unconcerned, believing that when Thomas is ready and wants to open his eyes, he will. These events instill a strong belief in free will in young Thomas. Two weeks after his birth, Thomas opens his eyes, apparently to look directly at his five-year-old half-brother Francisco. 1992 Julieta is a wife and a loving mother, working in a hospital emergency department. Her free-spirited youngest son, Thomas, is the product of her marriage to her second husband Alexandre. Pedro, her first husband and father of her eldest son Francisco, lives in Argentina. Pedro and Julieta remain good friends. During childhood, Francisco and Thomas are very close, perhaps too close according to Pedro, with whom they spend a Christmas holiday in Buenos Aires. Julieta is aware of their close relationship and tries to remain understanding. Not long later, Pedro dies. 2008 Years later, when Francisco is 27 and Thomas 22, Julieta dies. The brothers become lovers and an unusual love story ensues. Thomas is invited to live and train in Russia for a few years in preparation for the Olympics. Though it is the first time they will be apart, Thomas leaves. Francisco struggles without Thomas. He meets a woman in a club and though he tries to pursue a relationship with her, they both realize he is dedicated to someone else. Unable to be apart any longer, Francisco travels to Russia and the brothers reunite.
