Set in a small airline business, Cabin Pressure is a comedy about the wing and a prayer world of a tiny, one-plane charter airline staffed by two pilots - one on his way down, and one who was never up to start with. Whether they're flying squaddies to Hamburg, metal sheets to Mozambique, transporting lads on a stag night or shifting a panther for the odd oil sheik, no job is too small - but many jobs prove to be too difficult - for MJN Air!

The airline is run by forbidding divorcee Carolyn Knapp-Shappey who, at last, in her mid-60s, is free of her awful husband, but pleasingly not free of his private jet. Her two pilots are the smooth, experienced and almost certainly fired-by-a-big-airline-for-all-round-naughtiness Douglas, and the struggling, almost competent sweaty young captain Martin. General help is provided by Carolyn's dim-witted son Arthur.
