ITV drama Adultery follows a secret affair between two married parents

ITV's six-part drama Adultery follows an affair between Beth and Tom, two married parents played by Romola Garai and Dominic Cooper.

Beth is a mother whose fitness-training business has fallen apart, while Tom is a GP married to Hannah, who has been struggling with her mental health.

Their relationship begins after Beth knocks Tom off his bike, and the two start meeting in secret.

Both have spouses and teenage children, and their children are also dating each other, raising the stakes for both families.

The series also touches on grief, as Beth mourns her friend, and on the different pressures in each marriage.

Its final episode leaves the central characters facing choices about whether to turn their affair into a life together.

A second season has not been confirmed, and the team says the series was intended as a complete story, though they have not ruled out a return.
