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.

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?

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.

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?

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