Reparto principal

A dúo reparto completo

Liv es una cantante que conoce a su padre, Ricky Dean, en el entierro de su madre. Ambos participan en concursos de karaoke y acaban compitiendo entre sí. Al mismo tiempo, Todd Woods, un vendedor harto de su trabajo, de su familia y de su vida, recoge a un autoestopista y, durante el viaje, descubre con asombro que forman un excelente dúo musical.
