Back in the fifties, National Service came to all men. It came to Charlie Sage (Bob Monkhouse) during his wedding reception. And so, along with a host of other misfits, he found himself the next day sharing a bedroom with thirty other men, instead of with his new bride Mary (Shirley Eaton). Amongst the new recruits are Kenneth Connor's Horace Strong, a hypochondriac who is anything but strong - in mind or body; Charles Hawtrey's Peter Golightly, a man so innocent he wouldn't even admit to having been to the toilet; James Bailey (Kenneth Williams) who is less than impressed with the intelligence of his new colleagues; and Norman Rossington as Herbert Brown, still trying to pass basic training at his fifteenth attempt.
In command of this motley group is Sergeant Grimshawe (William Hartnell), for whom this intake of recruits will be his last platoon before retirement. And he's never achieved the one thing he craves – Champion Platoon. After a bet with his fellow NCOs, he's looking for a worthy last-ever platoon, and gets lumbered with the worst bunch he's ever known!
Whilst Grimshawe tries to whip them into shape, a task not easy when the person awarding the prize is the strict Captain Potts (Eric Barker), There's love in the air, as newly-wed Mary gets a job in the Barracks kitchen to be near her husband, and Horace Strong becomes the target for man-eater Norah (Dora Bryan).
This gentle introduction to Carry On falls well into the typical 1950s British Comedy film genre, with a few hints at the sauciness to follow. The cast perform their roles with style and energy, and the jokes are easy on the brain. It's far easier to watch Carry On Sergeant than something like Stripes, which tells the same story (but far more coarsely) and then goes all gung-ho USA on us. Stick to this film, and you'll do fine.
