Inspired in a true story. A twenty first-century neighborhood high school. Bittersweet stories about kids born both in Spain and all over the world. Antonio (José Coronado) is the principal of a high school in a downtown immigrant neighborhood. His aim is to avoid the school's closing and the scattering of the students. Along with Antonio's ever-increasing help, Judith (Belén López) the new music teacher, takes on the difficult task of obtaining her student's interest in her subject while helping them become active participants in a common project.
