Kath is planning her anniversary celebrations, while Diane is worried she's not got enough cheese for the soiree she's organising for the 'French Exchange people'. Meanwhile, Martin is under financial pressure and needs to make some big decisions - decisions that will end up impacting him and everyone close to him.

Diane is worried that she didn't impress the school governors, Kath is revealing more than she should, and Martin is desperately trying to get his hands on a chunk of cash.

Moneylenders move in on Martin's family, leaving him with no choice but to fight back. Meanwhile, Diane and Kath pursue Martin in the hope that they can work out what he's up to.

Kath visits Martin in his office and gets way more than she bargained for, and Diane's trip to the bank leaves her red-faced and running for the door.

Diane puts her trust in Kath and sends her on a covert mission while she reluctantly goes to dinner at Sandy Cooper's house with Martin. But will Kath be discovered?

It's the big day for Kath and Diane as they attempt to finally exact their revenge on Martin. But whilst Diane has never felt more alive, is Kath having second thoughts?
