Paranoia reaches breaking point for Joanna and Statham, and they're forced to take drastic action. Mac, Guy and Martin make an offer to Caroline that she can't refuse. Only she does. Or does she?

Caroline has to be cruel to be kind, while Joanna and Statham struggle to conceal the incident with the stuffed heron. Sue turns private dick and Martin comes into some money.

Statham is unusually cheerful, but it will probably end in tears. Mac finds it hard to adjust to his new role, Martin hires a private detective and Caroline has a hot date.

Dr Statham enters politics; at least the manifesto will be grammatically correct. Caroline thinks her choice of lodger might have been a mistake, but finds that she has to live with it.

Attractive single white Guy seeks accommodation, and a new member of staff upsets the apple cart (or whatever they use to transport patients these days)

A documentary crew are in the hospital, so everyone just has to act normally... well there's a first time for everything!

Guy has to live without a driving licence and Statham has to live without sex; will either of them survive?

Caroline has to cope with the aftermath of the ambulance crash, while Joanna has to cope with the fact she slept with her own son
