En un mundo nuevo(1972)

When spirited governess Karina arrives at a grand mansion to teach a group of musically gifted children, she brings harmony through song—but discord brews behind the scenes. As Spain’s top star Marta prepares for Eurovision glory, her composer boyfriend Carlos finds unexpected inspiration in Karina. Jealousy, ambition, and romance collide when Marta issues a dramatic ultimatum: either Karina leaves, or Spain loses its voice at Eurovision.
