On voyage to Perth, the MS Deutschland gets its unannounced new captain, former cruise ship steward and cargo captain Victor Burger. Cook Marius brought his motherless preteen son Jonas, who adores koalas. The captain takes to the cute rascal, unlike the mean chef. Jonas's grandmother, who was to chaperon him, is indisposed, so Marius brings in Claudia, a friendly maid. The knave goes missing after spotting a caged koala. Ship doctor Sander visits his Royal Flying Doctors mate Frank Marshal, who takes him along to an Aboriginals clinic. The airplane comes in handy to rescue two parties from the ship.
