The episode's pre-intro scene has Martin giving a cabin address in which he claims there's nothing to worry about. This goes on a few more times until he states he needs a stimulant made from a South American bean. Carolyn has Arthur send Martin a coffee.
The episode picks up directly afterwards, with Martin finishing his coffee and then Arthur seeing the Sahara desert and camels, which he considers to be "Brilliant". Douglas sets about landing, but a hydraulics failure makes Martin take the landing.
After a rough landing, Martin gets into an argument with the Douz airport manager over fees, refusing to pay them. Meanwhile, Carolyn realises they're doing this trip for free when she speaks to the Captain of the Panda Charters flight and finds out they've gone bankrupt and Jutteau wouldn't let them leave without paying the bill and so stripped their plane to pay for the bill, leaving them stranded in the airport.
Jutteau drains GERTI of her fuel and parks a number of vehicles around the plane, blocking them in until they pay the bill. Refusing to pay it, they think up an escape plan while Douglas plays cricket with the Scots international team.
Douglas gets a plan. He drains the fuel tank of the baggage carts and fire trucks, moves the fire truck out the way with the help of the cricketers. They taxi the plane out the runway and down the highway to the nearby airfield at Kebili.
The episode ends with Douglas and Martin driving GERTI down a deserted Tunisian highway, while Arthur has decided on the new MJN Air brochure cover, which is a dozen Scottish men in swimming trunks moving a Fire Truck.
