The fourth season of the critically acclaimed drama 'The Affair' will begin streaming on ITVX from Sunday, July 5, 2026. ITV released the first three seasons in March 2026, and the fourth season is now set to follow.
Star-Studded Cast and Plot
The series features Ruth Wilson, Dominic West, Maura Tierney, and Joshua Jackson. Originally premiering on Showtime in the US in 2014, 'The Affair' concluded in 2019, leaving fans disappointed. ITV's acquisition now brings the drama to UK audiences.
The show explores the emotional and psychological impact of an extramarital relationship that shattered two marriages, along with a criminal act that reunites the characters. Season four finds Noah (Dominic West), Helen (Maura Tierney), Alison (Ruth Wilson), and Cole (Joshua Jackson) in separate worlds, estranged from each other. Each character becomes entangled in a new romance, forcing them to decide whether to abandon the past permanently.
Fan Praise and Critical Acclaim
One viewer praised the show as 'the best TV show ever,' stating: 'They don't make TV shows like this. This is drama at its best. Superb writing and cast of actors, so much talent in this one show. I wished there were 10 seasons of this because it never gets old.' The fan added that season four is their favourite because 'we have travelled so far with these characters that they feel like friends now.'
Series Details and Availability
'The Affair' comprises five seasons totalling 53 episodes. ITVX has secured all five seasons. The first three seasons arrived on March 13, 2026. Season 4 is due on July 5, 2026, while season 5 will become available in 2027.
