Herman discovers he's the new lord of Munster Hall in England. The family sails to Britain, where they receive a tepid welcome from Lady Effigie and Freddie Munster, who throws tantrums because he wasn't named Lord Munster. An on-board romance had blossomed between Marilyn and Roger, but on land Marilyn discovers Roger's family holds a longstanding grudge against the Munsters.
