The scene is set as Dr. Rebecca Nelson, a world famous, Aborigine Marine Biologist, sets off to coordinate the Boat Voyage of Reconciliation, the crew of which plans to circumnavigate the Australian continent in support of the Aborigine cause. Rebecca expects a routine voyage but she is not aware of the adventures and deadly hazards she will encounter.

First, Rory McTavish, a handsome, outback Reverend is assigned to the voyage by his Bishop and then the vessel, under Rebecca’s command, encounters a massive fish kill from Cyanide on its Shake Down cruise. Finally, the lives of everybody on board and particularly Rebecca’s grandmother, Loonoodir, Grand Leader of the Queensland Aboriginal Councils, are threatened by a high Government official who plans to scuttle the ship in order to prevent Rebecca from investigating the cause of the Cyanide spill she has encountered.
