Following the advice of a dead friend, Guy, Mac and Martin decide to finally propose marriage to Caroline, with varying degrees of success. Alan and Joanna believe they are beyond the law, but not for long. Karen falls out of a window and Martin experiences a case of deja vu.
In probably the most eventful episode of the series, the only person with good news to share is Sue White, who after a rousing rendition of The Circle of Life gives birth to a lion cub.
Unfortunately, there is nowhere she can go to share the joy as Guy continues to proclaim his love for Caroline and tries to convince her that he is ready for commitment by proposing to her. However he faces some stiff competition from Mac and even Martin as they also have proposals to make. It looks as if Mac is going to be the lucky suitor after arranging to meet Caroline at the train station and take her away for the weekend. However, there is a large setback in the form of test results and Mac discovers that he may not have long to live. This leaves the path clear for Guy and Caroline instead (who don't know about the results) whilst Mac tries to come to terms with the news.
The news isn't any better in the rest of the hospital either, even for the Office Girls. Harriet's husband throws her out after he discovers her affair with Lyndon, and Karen falls out of the office window. Despite the fact she may have died, none of the rest of the office even notice she's gone.
Even Alan and Joanna are still having problems. First of all, Joanna takes refuge in Alan's cupboard after being wracked with guilt about the murder of her cousin and refuses to leave. Despite things beginning to look up for them both when the official verdict on the incident is suicide, things still become too much for them and they go on the run in a stolen motor home. And in an all too familiar scenario of a sheep, a cliff and a large motor vehicle, stowaway Martin experiences a little bit of déjà vu. But will they all be as lucky as the staff were last time round?
