 On 1969, in Argentina, the eight-year-old Valentin (Rodrigo Noya) is a boy that dreams to be an astronaut. He is raised by his poor widow grandmother Abuela (Carmen Maura), and is totally abandoned by his parents. His mother has apparently forgotten him, and his stupid father does not pay much attention on him. The smart, but needy kid missed his mother, and when his father introduces his new girlfriend Leticia (Julieta Cardinali), Valentin has a strong connection with her. Meanwhile his grandmother gets sick, and the boy tries to resolve all his family problems using his persuasion and viewpoint of life. He also tries to approach Leticia to his great friend and master Rufo.
