What is Adultery about?
Tom Kirkman and Beth Brookes are both married, with families of their own. Their teenage children are also together: Jess, Tom’s daughter, is 15 and going out with Beth’s son, Ollie. The two parents feel an instant pull towards each other, and as that turns into an affair, both households are put on the line.
We won’t go beyond that here. Episode 5 turns the spotlight on Tom’s wife Hannah and on Beth’s own history, and the finale is where the consequences land.
