Get Some In! is a comedy series about Jakey Smith, a reformed teddy boy who is called up to national service in the mid-1950s along with three others from contrasting backgrounds: slow-witted Scot Bruce Leckie, former grammar school pupil Ken Richardson and vicar's son Matthew Lilley. The four find themselves posted to 'C' Flight at RAF Skelton, where they come face to face with their permanent adversary, drill instructor Corporal Percy Marsh.
