All Along the Watchtower is a British sitcom that aired on BBC One in 1999, about an RAF site in Scotland, it was written by Pete Sinclair and Trevelyan Evans.
Far from being staffed by the 300 crew he expects, he is horrified to find the site is actually occupied only by the eccentric, obtuse and war-ready Wing-Commander Campbell-Stokes and his gauche junior Airman Tench.
All the other staff have been siphoned off over the years and never been replaced, resulting in RAF Auchnacluchnie receiving the full quota of supplies and budget for its supposed population.
Campbell-Stokes and Tench have been left to eat from 100 pint tins of baked beans, make tea from 100,000 bag boxes of tea-bags, and keep ready for a war that will never come.
Harrison decides to file a report recommending the site's closure, but meanwhile becomes smitten with Eilidh, the pub landlord's beautiful daughter.
