In a dreamlike journey through the memories that formed him, Sergio's past comes to life before his eyes. With his grandparents' house in ruins as a vehicle of memory, he will question his first 10 years of life and why he considers them his Prelude, the foretaste of what his life and work would become. Among ghosts, he will have to make peace with his memory, his reflection and his name to find the color among the ashes and stop fearing the future.
