Brazilian physics professor Zero (Wagner Mara Wagner Moura) is a genius whose behavior is perverse and has made numerous major inventions, but investors are increasingly unable to put up with his crazy behavior, so they unilaterally terminated their cooperation with him. Forced into a corner, Zelo secretly stepped up the particle collider experiment in order to open a time tunnel back to November 22, 1991. 20 years ago, Zelo met Helena (Alini Morez Aline Moraes), a beautiful girl from the same school. He had a crush on him and helped her catch up with her lessons, but his beauty and Helena's strong boyfriend deterred Zelo. He even suffered a life-long humiliation in the process. In order to change his life in which genius is useless, Zelo hopes to help his young self change the future and open up a different life.
