Adaptation of Mór Jókai's classic 19th century novel on Mihály Tímár, the captain of a commercial Danube ship in the 1830s, who finds unexpected fortune by meeting a Turkish aristocrat fleeing from his home country with his daughter Tímea. On their journey, they find an unknown island on the Danube, called the Senki szigete (the Island of No-one), a sort of earthly paradise, with only an old woman and her young daughter Noémi living on it.
