The fourth season of the hit-US drama series which tells the stories of two affairs and the emotional and psychological consequences they perpetuate reaches its climax this week with a double bill of shock-filled episodes. Dominic West, Maura Tierney and Joshua Jackson head the cast in this scandalous and shock-driven drama.

In a bid to salvage a relationship with Alison, Ben confesses the truth about his marriage but is it too little too late? Episode 10 then returns to the present. Still reeling from Alison's apparent suicide, Noah is confronted by his own actions when he realises he has moulded his star student, Anton, in his own image during an excursion to Yale, where he later encounters an old friend. An difficult day forces Cole and Luisa to re-evaluate their relationship while, elsewhere, Helen finds a new perspective on life. The Affair - Tuesday 9:00pm on Sky Atlantic.
