Instead of the cruise bringing them closer together, the Ransome's agree to get a divorce when they return home. Eileen disappears, and when Allan finds her she is wearing a nightgown that a passenger wore on her honeymoon. Seeing her, Allan realizes how much he still loves her. The passengers force them into a lifeboat, with plenty of provisions, and set them adrift. The Lady Anne sails off.
The series was a collection of various tales that range from the tragic to the comedic. They may be scary or just thought-provoking. Most episodes have unexpected endings and a moral lesson. But, no matter what, it's "a journey into a wondrous land, whose boundaries are that of the imagination".
