Madalena is a tough seventeen-year-old who is forced to take on her father's ferry business after he dies. She has her many brothers and sisters to support, and there is no one else to do the job. So she rallies her defenses and sets out to give her rival in the ferry business a run for his money. But at the same time, the rival's handsome son is starting to look better and better. Madalena refuses to acknowledge her feelings for him -- though how long she can sustain that denial is the question.

Hamburg, Germany, 1939. Getting a passage aboard the passenger liner St. Louis seems to be the last hope of salvation for more than nine hundred German Jews who, desperate to escape the atrocious persecution to which they are subjected by the Nazi regime, intend to emigrate to Cuba.

The plot concerns a Key West charter boat captain persuaded to help smuggle Cuban refugees to Florida. When a refugee is killed while escaping, he loses his license and becomes involved with a married woman, whose jealous husband wants him dead.
