Along the 80s years of La Movida Española (The Madrilenian Scene), Sinfín turned in one of the most important music bands of Spain. But in 1990, about to give its greatest concert in the Plaza of Las Ventas in Madrid, the singer Javi dies in his dressing room by drugs overdose, shocking to his friends, partners and the rest of the country. Fifteen years later, Sinfín's former manager Álex is now manager of Javi's younger brother, Iván, who wants to follow the steps of Javi to be a great singer and musician. Playing in road bars and towns' feasts Iván tries find his place in the music as well as himself while Álex plots a great idea: reunite all Sinfín's members to give the concert that they couldn't by Javi's death. Therefore, the mission is more complicated that it seems: drummer Hilario "Larry" works playing jingles for commercials, guitarist Nacho is a salesman of a shopping center dominated by his wife Puri, and bassist Rafa is music teacher in a high school. For more troubles, Rafa meets again former love Laura after 15 years without see her, who now works for Lucena, a successful but cheater music producer to who Álex tries to convince that the return of Sinfín is possible. Forced to give three small concerts to test Sinfín's popularity, troubles start from the beginning: the old resentments between Rafa, Nacho and Larry appear again causing several discussions, the own Larry and his bigmouth friend Kiko create messes wherever they go, the remember of Javi overflies Iván time and time again, fearing to end as him, and he interests about Laura, creating a bitter love triangle with Rafa. But the greatest trouble appears when Lucena exposes Álex his plans to promote Iván outside the band, causing a doubt in the rest to keep all together or leave Iván to find his own way, and about an incoming concert tribute to the 80s to celebrate in Plaza de Las Ventas. Will can they get participate in the concert and stay together before that they kill each other?
