*Bonkers last screened in 2007*

All the curtain-twitching horror stories about sexual habits in suburbia are laid bare in ITV1's new comedy-drama Bonkers.

The six-part, sex-packed series stars Liza Tarbuck as a likeable Liverpool school teacher, Helen, who's married to Tony, a struggling soap writer played by The Full Monty star Mark Addy.

On their 20th wedding anniversary her life is thrown out of its comfortable but messy domesticity when her 19-year-old ex-pupil Nicole announces to the anniversary party-goers that she and Tony have been having a three-year affair.

"I think this revelation is really the final straw for Helen," says Liza. "You get a hint at the end of episode one as to how mad she really is. She basically has some kind of breakdown when she hears the news.

"I think you look at Helen thinking she's the only mad one, but everybody is mad. No one in Bonkers is completely stable!"

While her marriage and life appear to be in tatters, somehow out of that turmoil something completely bonkers, involving film star called Felix Nash, leaves her feeling on top of the world.

Lisa says: "I do think she's at the age in her life when she has space in her head to wonder what it is you would like to do and rather than change anything about herself she has developed a fantasy life - and an extremely vibrant one."

Coming from the pen of Sally Wainwright (creator of At Home With the Braithwaites and The Amazing Mrs Pritchard) Bonkers will provide some quality comedy to balance out the often dismal tales behind sexual relationships in the suburbs...

Everyone is obsessed with sex in Bonkers. Helen and Tony's son Tim has an oversized libido, even for a 20-year-old, and starts an affair with their middle-aged neighbour Mrs Wadlow (Lynda Bellingham); Helen's younger brother Marcus is a handsome solicitor, but he's horrified by his wife Imelda's attempts to pep up their sex life; and Helen's other brother Stewart discovers his fianc�©e in bed with his nephew Tim.

Confused? As the similarly bonkers 1970s sitcom Soap used to sign off - you won't be after this week's episode.
