Sergeant Grimshaw wants to retire in the flush of success by winning the Star Squad prize with his very last platoon of newly called-up National Servicemen. But what a motley bunch they turn out to be, and it's up to Grimshaw to put the no-hopers through their paces.
The professional skill of William Hartnell and Dora Bryan lends some reality and humour to this conventional farce, in which all the characters come from stock.
