Doctor in Trouble (1970)

Dr. Burke harbors feelings for Ophelia, but with her departure for a Mediterranean cruise, he struggles to find the right moment to propose. On the same ship is an old college friend who stars as 'Dr. Dare' in a wildly popular TV show, attracting admirers wherever he goes. Determined to be near Ophelia, Burke sneaks aboard the cruise, only to be caught as a stowaway and later appointed as the captain’s steward. As he navigates his awkward attempts to connect with Ophelia, he encounters a quirky cast of characters, including a lucky gambler and a particularly obstinate captain.
