Under-deodorized, Dr. Todd arrives at her new job after spending the night in her car. Her first day gets no less hygienically and professionally challenging as she meets her colleagues.

Caroline spends the day quashing rumors about her night at Guy's flat, while Guy unquashes them. If only she had something over him. But he won't blurt out a dark secret, will he?

Joanna worries about her age. Who wouldn't, at her age? Her dangerous liaison with Alan Statham is becoming tedious, she demands spontaneity. He agrees to think about it.

It's Joanna's birthday. What does a man get the woman he worships for her birthday? Would it be a locket filled with his own love juice?

Martin is desperate (not just generally, although that's obviously still the case). He's worried that he hasn't got anything to wear to Caroline's housewarming party.

It's a testing time. Joanna and Harriet are each convinced they're pregnant, Martin sits his exams for the hundredth time and Mac surreptitiously interviews for a promotion.

Caroline is broody, but she's confused. Is Guy the good guy or the bad guy? Is Mac the good Mac or the bad Mac? Martin gets his exam results.

Martin loves Caroline. Caroline loves Mac. Mac has a girlfriend. Statham loves Jesus, or is it the chaplain? Joanna loves Lyndon. And Guy pretends to love Caroline.

Joanna is desperate to lure Statham away from Jesus. Caroline is desperate to lure Mac from his girlfriend and Sheffield. In one final bet, Mac challenges Guy that he can't bed Joanna.
