There was no pre-credits scene so we start with the crew in New York preparing to return home to Fitton. Carolyn tells them that they have another job to which there's complaints as they have to go to Toronto and then pick up a bunch of passengers and then take them to Qikiqtarjuaq to see Polar Bears. Martin is upset cause he'll miss his job with Icarus Removals and he also explains that he can't use a jet aircraft to see bears.
They play a cockpit game, this time inserting as many Alfred Hitchcock movies as they can into the cabin address, and to which Douglas goes first, saying "Hallo. My name is First Officer Douglas Richardson. On behalf of the captain and myself, a warm welcome aboard this MJN flight to Qikiqtarjuaq. Just to let you know we will be flying out from Toronto today, roughly “North by Northwest” at the “Vertigo”-inducing height of twenty thousand feet, way above “The Birds”. You will already have met your purser today, Carolyn “Rebecca” “Topaz”, but now, as “The Lady Vanishes” behind the “Torn Curtain” into the galley, the steward will hold you “Spellbound” with his “Notorious” demonstration of “The Thirty-Nine Steps” to a safe evacuation, though these basically boil down to three: pull the “Rope”, inflate the “Lifeboat” and escape through the “Rear Window”." Then, after this, they're counting up how many they got when Nancy comes in and berates Martin for acting unprofessional on the flight. He promises to behave and make Douglas behave too, which infuriates Douglas, making him plot revenge on Martin.
In the flight deck, Nancy tells Carolyn to refer to the flight as an Unbeaten Track flight and not MJN. Furious, Carolyn goes into the flight deck while Martin and Douglas are still having their little spat over professionalism. Carolyn decides that it's time for fun and games with the Unbeaten Track people to while away the time. Douglas suggests the Travelling Lemon, in which a player must place a lemon in the cabin, in public view and the other person must find it. While Douglas is in the flight deck, hiding the lemon, Martin tries to negotiate for some pay, but fails to do so. Douglas announces the lemon is in play.
Carolyn spots the lemon in a woman's purse as she makes her a drink. Douglas forces Martin to be Captain DuCreff, a French pilot in a prank. Although he had his finger on the mute button. Nancy berates him again for the prank and he tries to come across as being professional. Douglas goes to hide the lemon again and leaves Carolyn with Martin. He explains to Carolyn that he's a man with a van and needs money. He lives in the attic of a shared student house. Douglas returns with the Lemon and promises to Martin that if he finds it, game over.
Martin goes out to find the lemon and fails. Arthur tries to explain to Nancy that he's an expert on bears and wants to do a lecture. Back in the flight deck, Martin apologises for starting the fight and wants to end it. Douglas has him do another story as Captain DuCreff, again with his finger on the mute button. During this, Arthur comes in and screams "BEARS!" Douglas forgets he swapped everything over as he goes after the bears, screaming and laughing as he flies over them. When they finish, the Unbeaten Track people are frozen to their seats in fear at what they just heard.
As they leave, Arthur gives them Farewell Bear Facts and Nancy tries to stop them from calling it Unbeaten Track, asking them to refer to it as MJN. Martin confronts Nancy and tells her that he IS a professional, giving a stirring speech about his crew. The episode ends with Nancy telling Martin that he has a lemon taped to his hat.
