In the episode, Del puts together a consortium to buy a set of 18 carat gold chains from a retired jeweller.
Arnie explains that he acquired the chains several months ago for another man, Maxi Stavros, but has not heard from him since, and now he is willing to sell them for half their wholesale price.
However, seconds after the deal has gone through, Arnie calls his wife, who informs him that Mr. Stavros has made contact and now wishes to purchase the chains.
Arnie is distraught as he has shaken on the deal and worries about having to explain to Mr. Stavros that he has sold the chains, with the threat of violent reprisal hanging over his head.
Del gives it a try, but comes up short and gets put through to the Highcliffe Hotel in Guernsey (Rodney had phoned to contact Cassandra).
Now resigned to losing the gold chains for good, a despondent Mike, Boycie, and Trigger leave the flat.
A few days later, while picking up Cassandra at the airport, Rodney spots Arnie, this time in west London, being carried into an ambulance by two paramedics.
The next day, at an Indian restaurant, Denzil and his brother Carl are keeping an eye on Arnie from a nearby table.
