Bontekoe's Young Sailors

Three boys embark on their first sea voyage and find themselves shipwrecked
on a tropical island.
Hajo, Padde and Rolf, teenagers from a dutch harbour town set out to sea as members of captain Bontekoe's crew. The ship is bound for exotic lands, and everyday introduces the boys to new challenges.
When approching Java, a fire breaks out which destroys the ship. The boys manage to reach land but it's not the haven they expected. The island natives are intent on killing them, but one of the local girls, Dolimah, befriends the boys and leads them on a perilous journey through the jungle to safty.
Hajo and Rolf desperately want Dolimah to return with them but she is too afraid of the unknown world beyond her island. So the boys continue on with out her and finally reach Bontekoe who, in his new boat, is about to set sail back to Holland.
