A technical problem aboard a transatlantic flight forces a plane to land in Porto Santo, the small island of Madeira's archipelago where, according to a legend, Christopher Columbus the 15th century navigator, lived for a while and entertained a sexual relationship with a widow and her nubile daughter. A girl photo journalist profits to stay the extra-needed days for repair, to visit the island - and eventually she'll become part of complex relationships among some of the secluded people of the island. Also, a yacht lost in the high seas in 1947 reappears from the misty horizon 50 years later - to unite Fanny and João, a contemporary navigator.
