Struck by cholera, the crew of the ship start to die and the captain sets Sarah, Richard, Lilli and a healthy crew member on a lifeboat in an attempt to preserve their lives. Taken in by Sarah, a widow with an infant baby girl Lilli, Richard (Paddy) is cared for in a return to civilization. Established in the first film, the only word Paddy ever says is "Richard", so the crew assumes Richard is the infant's name. We open the film with a ship finding the craft with our original characters in it, Richard and Emmeline dead and Paddy alive.

While the general theme of this film resembles "The Blue Lagoon" (the film for which this is a sequel), the basic plot is quite different.
