Héctor—concertmaster of the Tenerife Symphony Orchestra—is torn between guilt and the tremor that threatens to silence his career. Ten years after his daughter’s death, and at the urging of his former psychologist—who is also his best friend’s wife—he agrees to participate in a restorative justice process with the man convicted of the crime. What begins as a head-on collision between two wounded worlds turns into an uncomfortable search for the truth. However, when an old violin reappears on the scene, Héctor finds himself entangled in a web of secrets that calls into question everything he thought he knew about his daughter… and about himself.
