Still on their cruise around the world on a wooden clipper ship, the Sara Ann, Clark and Jimmy face new dangers.
Superman has just rescued the battered ship from the storm, and as Clark, he has been acting as doctor to mend the wounded captain. The medical danger isn’t over yet, and Barnaby suspects that Clark is up to something as he takes charge. Can another doctor be radioed from a near by ship? Why is Barnaby so upset over Clark’s intrusion? Though the storms in the weather and medical conditions reach a calm, there’s new trouble brewing among the crew.
