From the dawn of man to the Battle of Jutland, the Ambrose family tree has always maintained its ability to create a long line of distinguished naval officers… until now. Captain William Horatio Ambrose has tried hard to preserve his family’s tradition, but unfortunately suffers from chronic seasickness; just the mere mention of anything slightly nautical or aquatic sends him overboard. Once again, screen great Alec Guinness manages to create another unforgettable comic creation for the last film he made with the legendary Ealing Studios.
