This second entry in the British "Doctor" series once more stars Dirk Bogarde as young medico Simon Sparrow. Securing his first job as ship's doctor on a freighter, Simon again runs afoul of James Robertson Justice, here cast not as the irascible Sir Lancelot Sprat but as ship's captain Hogg. Unexpectedly, the freighter is obliged to take on passengers--specifically, the man-hungry daughter (Brenda DeBanzie) of the shipping magnate who owns the vessel, and toothsome French chanteuse Helene Colbert (Brigitte Bardot, in her first English-language film). As the older woman makes a play for the crusty captain, Helene sets her sights on the nonplussed Dr. Sparrow. Often funnier than its predecessor, Doctor at Sea proved the viability of the "Doctor" series, prompting several chucklesome sequels.
