Nina meets the new paediatrician; Cherie has a surprise for the Proudman family.

Nina hopes that once her mildly psychotic ex-husband is caught by the police, she will be free to pursue a hot and steamy relationship with Chris - but he seems distracted.

Nina is caught off guard when she meets an unconventional couple wanting a completely nude birth. After being labelled a prude by her co-workers, she is forced to confront her own insecurities.

Believing she interrupted Chris and Zara having sex in the storeroom, Nina spends a sleepless night struggling with her feelings. When Chris finally corners her to talk, Nina protects herself from further humiliation.

As she is plagued by fantasies of Chris Havel, Nina is stunned to learn that his wife has been missing for more than a year.

Nina and Chris attempt to seize the moment, but their future is threatened by a complicated past. Elsewhere, Cherie's secretive behaviour prompts Billie to start playing detective, and Jimmy and Odile come to a crossroads in their relationship.
