The film contrasts Mike Squires' previous life - a "pretty ordinary" existence consisting of TV and the occasional game of snooker - with his exciting career as a soldier in (?) Duke of Wellington's Regiment, HQ Land Forces Hong Kong. Sequences show two RAF Whirlwinds airlifting troops, men at drill, and Mike off duty, playing squash and relaxing with a bikini-clad girlfriend. Mike is a trained infantryman, "the pace is faster, and you've got to know what you're doing. That's why they're called the Professionals."
