Set on March 25, 2016—the historic day The Rolling Stones played a massive free concert in Havana—Molina, an eccentric former teacher of scientific Marxism and obsession-driven rock fanatic, is torn between his devotion to Mick Jagger and the unexpected return of Margarita, an old flame. As the city buzzes with rock 'n' roll fever, Margarita re-enters Molina's life, bringing along complex sensual desires and physical entanglements that derail his long-awaited pilgrimage to the concert.
