Bumbling Seaman Blissworth (Kenneth Connor) accidentally destroys the vital top-secret wiring plans for the new experimental Acoustic Torpedo Mk2 (codenamed “The Creeper”) and spends the rest of the film trying to cover up the fact, donning several disguises to get his hands on the only other copy before the peppery Admiral Sir Humphrey Pettigrew (Noel Purcell) arrives to visit HMS Terrier and view the plans.
Matters are further complicated when the scientifically-inclined Blissworth becomes involved with Agatha Potter (Hattie Jacques), a female scientist from the Admiralty, and discovers a fault in the wiring of the torpedo.
Firing day arrives, and everything dissolves into one big explosion of laughter as ‘The Creeper’ runs wild and scares the bellbottoms off the Navy.
With Kenneth Connor, Hattie Jacques, Joan Sims and Sid James starring, Gerald Thomas directing, and Peter Rogers producing, it can’t help feeling like an early Carry On film (without the innuendo).
Future Love Thy Neighbour star Jack Smethurst has a small part as a sailor.
