A young Argentine woman takes part in a TV quiz show in Buenos Aires, answering questions about Rio de Janeiro. As her prize, she wins a trip to the Marvelous City, where she lives a week-long daydream, swept along by the most beautiful songs and enchanted by Rio's landscapes. Seven days stirred up by the comings and goings of three leading men: an aviator, a playboy, and a journalist. Like a magic kaleidoscope, the three parallel stories unfold in a whirl of amusing and romantic situations, as all three end up falling in love with her. Like every dream, the young tourist's must also come to an end: she has to return to Buenos Aires. Only there, far from Rio's spell, will she finally choose the one she truly loves. The first Brazilian color film shot in CinemaScope.

The film won the Brazilian Association of Film Critics Award for Best Film, the Governor of the State of São Paulo Award for Best Producer for Carlos Hugo Christensen, and Best Actress at the Federal District Festival and the Saci Award for Best Actress, both for Suzana Freire.
