Nighty Night

Jill is picking up the pieces of her life after the murders at the end of the last series. She has managed to frame ex-boyfriend Glen for them.

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 decides that the only way left to infiltrate herself into the Cole household is to emulate Cath's pregnancy, and announces that 12-year-old Bruce is the father. Don responds by going into a persistent state of drunkenness.

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.

Jill, the owner of a suburban beauty salon, sees her husband’s terminal illness as a fresh start for herself. She immediately falls for new neighbour Don, who moves into the house opposite, with his wheelchair-using wife Cathy.

Jill descends further into Cath and Don's lives by inviting Don around for a dinner of smashed prawns in a milky basket. However her plans are thwarted when Cath turns up for dinner too. Meanwhile, husband Terry continues his attempts to get in touch, but Jill still refuses to speak to him.

Jill convinces Cath to try to heal her marriage with the Caro Bibbens Celebrating Celibacy programme. Don becomes increasingly frustrated and is eventually thrown out of the house by Cath after she finds a pair of lacy split pants in his pocket.

Don attempts a reconciliation with Cath but Jill is now firmly established in their home and has no intention of allowing the two to make up. Meanwhile, Terry is released from the hospital and Jill puts him straight into a hospice where he assumes he'll spend the last days of his life.

Cath finally stands up to Jill and throws her out of the house and reveals some interesting news to Jill. Jill goes ahead with Terry's funeral, inviting Cath & Don, however there is one guest Jill did not expect.

Don and Cathy split up. Jill kills Terry, then forces Glenn to kill Gordon the vicar with a poisoned sundae and makes him confess to the police. Then she tells them him they can start a new life- well death together. He eats one of the other poisoned desserts, then gives it to her, saying it's her turn. She tells him she's not really hungry and watches him die. Terry turns out to be alive after all.
