The new season of Club 57 brings us unusual adventures and new challenges for our favorite characters. Eva and Rubén divide their time between 1957 and 1987, where the Guardians of Chaos have JJ hidden. But, this time, they are not the only boys jumping in time. Tiago, a brilliant but rebellious classmate, develops his own technology to jump through time. Soon, his spontaneous and disorganized trips collide with Eva and Rubén's plans. Although she doesn't like Tiago, Eva needs him to find a formula that allows her to be with JJ without tearing the fabric of time and causing chaos in the universe... once again!
