Julio Medem directed this romantic Spanish drama with location scenes in Finland. School children Ana (Sara Valiente) and Otto (Peru Medem) are brought together when a paper airplane flown from a window by Otto unites Ana's mother Olga (Maru Valdiviesio) with Otto's father Alvaro (Nancho Novo). After this encounter, Olga and Alvaro fall in love -- with the result that Alvaro leaves Otto's German mother Ula (Beate Jensen). To be near Ana, Otto begins living with Alvaro and Olga. Ana believes that Otto harbors the soul of her dead father. As adolescents, Otto (Fele Martinez) and Ana (Najwa Nimri) share a kiss over a book opened to a passage about the Arctic Circle, and they often sleep together. Otto is grief-stricken by the death of his mother -- partially due to his leaving her for Ana. Shown at 1998 film festivals (Venice, Toronto).
