New York City
Returning to England after 18 years, Mrs. Clandon and her three children — twins Dolly and Phillip, and Gloria
— readjust to British life at a summer resort. In this comedy of errors, the children unintentionally invite their estranged father Fergus Crampton to a lunch. The resulting awkward family reunion is witnessed by family lawyer Finch McComas, who finds himself the butt of the twins’ jokes. Meanwhile, Valentine, a dentist, falls for modern woman Gloria, whose ideals don’t include love or marriage. And through the chaos and the madness, kindly waiter William dispenses wisdom with the familiar refrain of “You never can tell.”
