Adultery

9pm, ITV1

“Attraction plus obstacle equals excitement.” This is the risky life motto that bored, put-upon personal trainer Beth (Romola Garai) takes to heart after her best mate unexpectedly dies. Wife to a useless husband and mother to an ungrateful son, it doesn’t take much for handsome doctor Tom (Dominic Cooper) to catch her eye. But Tom also happens to be the married father of Beth’s son’s new girlfriend. Created and written by Bafta winner Danny Brocklehurst (Shameless, Brassic), the addictive drama follows a steamy, sex-packed affair over six episodes – and the fallout from it. While the opener remains pretty PG, we’re promised trysts in cars, toilets … and a city farm. Hollie Richardson
