The special continues the plot from the end of the second series of Green Wing, which ended with Caroline Todd (played by Tamsin Greig) becoming engaged to Guy Secretan (Stephen Mangan), "Mac" Macartney (Julian Rhind-Tutt) learning that he was going to die, Alan Statham (Mark Heap) and Joanna Clore (Pippa Haywood) fleeing from the police after they murdered Joanna's cousin, and Karen Ball (Lucinda Raikes) having a dramatic change of personality after she fell out of a window.

[2] While this was the final episode of Green Wing, an alternative ending was produced in case a third series was written.

[1] The episode begins at a funeral, attended by Guy, Caroline, Boyce (Oliver Chris), Martin Dear (Karl Theobald) and Sue White (Michelle Gomez).

References made in the episode lead the viewer to believe that it is Mac's funeral, but then a giant picture of Angela Hunter (Sarah Alexander), who left the hospital in mid-series two, appears.

[3] The cause of her death is not fully explained, although comments made by the characters indicate she died in a hunting accident with a moose.

Alan and Joanna have an argument about the minute odds of the policeman having a peanut allergy and going into anaphylaxis, while in the background this is actually happening.

As Alan is not keen on the Spanish, they choose the third option and are last seen walking naked into the sea, presumably to their deaths–– although the alternate ending shows them hanging on to a buoy some time later.

Martin is captured by Naughty Rachel (Katie Lyons), Kim Alabaster (Sally Bretton) and Karen, chanting "Kill the doctor" at him.

The script was written by the usual eight-person team led by Victoria Pile, and produced and directed by the same people who recorded all the previous episodes.

In the beginning funeral scene, one of the mourners is Alan Yentob, who had been filming an episode of the BBC One documentary series Imagine.

[9] The opening titles of the episode differ from the others as it does not use the normal theme tune, "Last Week", (as it is named in the original television soundtrack) and instead uses the track, "Camel".

This is because the crew at the time had a crane camera after they had finished filming the final scenes in series 2 where Alan, Joanna and Martin are teetering over the edge of a cliff in the stolen camper van.

[12] The wedding was shot at Hall of Bayham Abbey in Kent, where the crew had difficulty filming due to bad weather.

Caroline begins to descend, and both Mac and Guy grab hold of one her legs to bring her down, but instead they are lifted into the air with her.

Speaking on the commentary, Rhind-Tutt says that he was glad that after much discussion they chose the ending "they all wanted", with "the three of them flying off together", however, this was not the version that was eventually broadcast.

Matt Baylis said, "Like a homegrown ER on laughing gas, this show will be sorely missed,"[1][17] and Ian Johns said, "It was like a Richard Curtis romcom, albeit one force-fed magic mushrooms.

Wollaston opined that while the dramatic elements of the show, such as Mac's death, were good, Alan and Joanna's storyline was most entertaining.

[19] David Butcher in the Radio Times wrote that, "Green Wing's sublime comic acting and a vein of shrieking madness in the writing make it very hard to beat.

"[21] Fans of the show thought that while the special was good, it was not the greatest episode of Green Wing made.
