Commander Bonar Colleano and his bride, Diana Decker, have just been married. He has been reassigned to London, so they plan to honeymoon there. When it hits the newspaper, up pops Diana Does; she's his first wife and, because he was divorced in California, they're still actually married. She turns up at the hotel, which makes the marriage celebration awkward. Afraid to tell Miss Decker about the situation, Colleano stashes Miss Does in the hotel suite's guest bedroom, and calls in his British lawyer, fuddy-duddy David Tomlinson.

It's a brittle, sexless sex comedy, but all hands show themselves excellent farceurs in Maurice Elvey's adaptation of a stage play by Vivian Tidmarsh. Elvey concentrates more on cuts to keep this moving among the three or four sets that make up the venue.

One of the peculiarities of this production is that despite all the American characters, few of them are played by Americans. Sid James plays Colleano's aide, and it's peculiar to see the man with the dirtiest laugh in all of show business playing a woman-hater. Lou Jacobi has a small role in his screen debut. Even if you don't recognize his form before he put on a lot of weight, you can't mistake his voice.
