Premise

According to ABC Weekly the play was about "a group of men who, together with the captain’s wife and little son, are the only survivors from a shipwreck. The party drift in an open boat on the Southern Ocean, and when at their last gasp reach a barren island, where they live on seal meat. The play’s story is carried forward by a poetic narration which brought forth high praise from the judges. It dramatises the adventures of the boat’s party with notes of hope and tragedy."
