Natalia is to be married to a German sailor much older than herself, but two days before the wedding she meets Diego, a mysterious young dancer, and they fall immediately in love. When he serenades her on the eve of the ceremony, Natalia's father unwittingly invites him to the festivities.

Soon after the marriage Natalia's father dies, and her husband is lost at sea, presumed dead. Penniless and alone, Natalia is persuaded to become a dancer in a tango hall. Diego discovers her there and vows to bring her away from this existence, but their reunion has devastating consequences. Many years later, the spirit of the dance and the lovers' longing for each other draws together two strangers in a haunting meeting, a fusion of time and identities, despair and hope.
