La Buena Voz (aka The Good Voice) explores the relationship that develops between a father and a gay son he never knew existed -- two men suddenly and unexpectedly thrust into each other's lives. Pepe, a slightly listless, fifty-something taxi driver with a heart condition, suddenly learns that he fathered a child, Jordi, from a quiet affair with his wife's girlfriend. Jordi, now HIV-positive, enters Pepe's world and recolors the elder's perspective and outlook on life, with his take-no-prisoners zeal for living and a restless, inquisitive spirit.

Narra la historia de Pepe y Rosa, un matrimonio de inmigrantes que nunca tuvo hijos. La vida transcurre con monotonía tras 27 años de apacible y rutinaria existencia en el País Vasco, su tierra de acogida, hasta que aparece Begoña, una antigua amiga de Rosa que revelará un secreto guardado durante casi 30 años.
