The pre-intro scene features Arthur in the flight deck. He makes a cabin address proclaiming to be Wing Commander Sir Arthur Shappey and he's undertaking a round the world record attempt. Even going as far as saying that people can jump out the plane at bits of the world they like best. He also wants to fly under the Sydney Harbour Bridge. Carolyn stops his fantasy address and reminds him to start hoovering.
The episode begins with Martin, Carolyn and Arthur in the Portacabin waiting for Mr. Goddard. It's raining and the cabin is leaking. Douglas arrives 45 minutes late and offers to make everyone tea. Arthur asks Douglas what song he was singing last week, but his singing is horrific. Douglas thinks it should be taken to the vet. Athur goes back to fixing the leak in the roof but falls through it, making the hole bigger. They decide to go sit in GERTI, at least where they'll be dry.
Inside the plane, Arthur offers to play Charades, despite the fact that last time he played, he mimed Apocalypse now, despite not knowing what an Apocalypse was. He goes back to working out what song Douglas was singing, but now has a different tune coming out. Martin goes through the Standard Operating Procedure notebook and Fire Evacuation procedure. Carolyn and Douglas make fun of him and he storms out the flight deck and towards the back of the cabin. Carolyn gets a phone call from Gordon Shappy, her ex husband stating that he wants to buy GERTI for £1 and he'll take on all of MJN's debts as well.To which, Carolyn is considering taking the offer.
Douglas goes into the back to apologise to Martin for being childish. They share the joke before Arthur comes in and explains that he was going to be a pilot too, but he never went up. Douglas and Martin discuss what it means to be happy, but Arthur explains what true happiness is like, His moments of true happiness are when you get in the bath and it's just the right temperature, or when your knuckles are just right for cracking and best of all, simply tossing an apple from one hand to another. Douglas, Martin and Arthur start juggling apples between themselves and that's when Douglas starts humming the song that Arthur was strangling earlier, which is "We're Busy Doing Nothing".
The crew believe that Goddard isn't coming as it's one hour to Dusk and he hasn't shown up or called. This is when Douglas reveals that the water they've been drinking has actually been vodka all along. They're all drunk except Arthur, who's been drinking pineapple juice. They're playing a game of "Books that sound different with the last letter knocked off". Goddard calls and he'll be there in 20 minutes. The only problem is Martin and Carolyn are drunk.
Martin and Carolyn are the stewards with Martin pretending to be Arthur. They joke about it to Goddard, who demands to see the pilots. He's unhappy they're throwing apples, despite Douglas insistence that it's hand-eye co-ordination exercises. They take Goddard to Madrid. The episode ends with Martin going to Douglas' house to give him back a present he left on the flight deck and this is where he finds out he's been lying to Helena about being a captain.
