Jill and Linda drive down to Cornwall as Jill goes in search of Cath and Don. On the way, Jill runs over a black woman and discovers that she was going to a job interview at The Trees, the therapy centre where Cath and Don are. Jill decides to take her place at the interview, despite the obvious difference in appearance.

Jill arranges an encounter with Don's girlfriend in an attempt to discourage her, while Cath pursues a relationship with her therapist.

Jill is still pursuing Don, even after finding out that Cathy is pregnant with Don's child, but her attempt to seduce Don is unsuccessful, so she seduces his 12-year-old son instead.

Jill's lies are finally catching up with her. The man she framed for her husband's murder, Glen Bulb, escapes from the mental hospital. And Cath is becoming suspicious of Jill's "pregnancy", which is now entering its 11th month.
