Zero is a genius scientist who tries to find a new power source into the lab of a college university. When he finally finds the solution and the miracle comes, he finds himself back to time and exactly when he was a teenager, full in love with Helena, the most beautiful girl in college. He tries to change the future and avoid public humiliation from her who left him furious for the rest of his life. But he complicates things more than he ever thought and his alter ego alongside with other characters from future built a surreal past where crazy situations come to reality. A great science fiction comedy from Brazil where Wagner Moura delivers an amazing performance and justifies his place as one of the best actors in Latin America.
