Jakey Smith is a Teddy Boy who's called up to do his National Service in the Royal Air Force.
During basic training, he shares a hut with Ken Richardson, Matthew Lilley and Bruce Leckie.
He also has to endure the disapproval of Corporal Percy Marsh.
Only four members of 'C' flight are unlucky enough to spend Christmas at RAF Skelton. Christmas is bad enough away from home for the first time; Christmas with Marsh as a demonic Santa is just plain misery.
