Doctor in Clover is another 'Doctor' movie, but this time Leslie Phillips is the main doctor in the story, looking for love and romance from the hospital nurses, much to the annoyance of the main Administrator (James Robertson Justice) who wants his doctors to be 100% focussed on the job. Numerous antics follow, with Phillips getting Justice fixed up with the new prim-and-proper Matron (Joan Sims) and his attempted failures to lure the hospital's beauty, the physiotherapist.

Detective Scobie Malone accepts a mission to fly to London to arrest Sir James Quentin, a high-level commissioner wanted down under for murder. But when Malone arrives, he finds that the amiable Quentin is not only the key in groundbreaking peace negotiations, but also the target of an assassin himself.

Losing out to Dr. Bingham (Michael Medwin) in a competition for house surgeon when he offends a member of the board, young Dr. Simon Sparrow (Dirk Bogarde) finds himself going from post to post, filling in for other physicians. At one distant country post, he is taken aback when he works with a patient whose husband died after Simon treated the man years before. In another hospital, Simon examines a surprisingly mature teen and also tries courting devoted nurse Nan McPherson (Shirley Eaton).

When Newman decides she doesn't want to be burdened with children, she decides to take the pill--which, as we all know from those ubiquitous posters of the 1960s, was a "No No" so far as the Pope was concerned.

After leaving the British Secret Service, David Somers (played by Trevor Howard) finds work cataloging butterflies at the country house of Nicholas and Jess Fenton. After the murder of a local gamekeeper, suspicion (wrongfully) falls on their niece, Sophie Malraux (Jean Simmons). Somers helps Sophie to escape arrest and they go on the run together. After a cross-country chase they arrive at a coastal city with the intention of leaving the country by ship. All's well that ends well after the true identity of the murderer is revealed.

Captain Vinka Kovelenko defects from Russia, but not for political reasons. She defects because she feels discriminated against as a woman. Captain Chuck Lockwood gets the order to show her the bright side of capitalism, while she tries to convince him of the superority of communism. Naturaly, they fall in love, but there's still the KGB, which doesn't like the idea of having a defected Russian officer running around in London.
