It's 2151 and the British have launched a fleet of space ships to explore the galaxy in the only way the British can… with a stiff upper lip and regular tea breaks. Their mission? To export all things British to all corners of the galaxy - namely overpriced supermarkets, housing estates, call centres and even tractors - and protect Britain's interest in a changing galaxy.

At the forefront of this expeditionary force is the HMS Camden Lock, helmed by the irrepressible, if a little tetchy, Commander Henderson (Nick Frost, of Shaun of the Dead and Hot Fuzz fame). Ably assisted by a crew of misfits, the Commander steers his ship through the stars, giving orders from his big swivelly chair.

Henderson is often more concerned with securing his place in British history than just doing his job. His crew? Borderline psychopath First Officer York (Kevin Eldon), sycophantic Diplomatic Officer Teal (Miranda Hart), manic depressive Navigator Vine (Stephen Evans), loose cannon Technical Officer Jeffers (Dan Antopolski) and enhanced human Sandstrom (Petra Massey).
