The Serial Killer's Wife | Preview (Channel 5)

This intense four-part drama is set in a family home nestled in an idyllic English town, where Beth Fairchild (Annabel Scholey) has prepared a surprise birthday party for her husband Tom (Jack Farthing).

With most of the village present as Tom is the beloved local doctor, Beth’s world is turned upside down when the party is interrupted by the police and Tom is arrested for the murder of his former assistant.

Episode 1: Beth believes her husband has been wrongly accused, but as cold cases re-open and more dead women are linked to Tom, Beth’s own past becomes headline news, leading her to seek help from Adam (Luke Treadaway) her husband’s best friend.

As Beth peels away the layers of her supposedly perfect life, she is forced to confront disturbing questions about herself and her marriage: has she ignored signs of her husband’s violence all along? And does she truly know the man she vowed to spend her life with?

In this first episode, Beth is determined to protect her family and reputation, and provides Tom with an alibi, leading to his release. But a discovery soon casts doubt on Tom's innocence…

Episode 2: Confronted with some uncomfortable truths, Tom confesses to some of the things he is accused of, but adamantly denies any involvement in the murder.

Meanwhile, Beth discovers evidence leading to somebody else in the community being the prime suspect, and goes to the police. However, that person retaliates by viciously attacking Beth and reveals that Tom was in fact present near the crime scene…

Episode 3: In the penultimate episode of the startling family drama, Beth turns to Tom’s best friend Adam for help as she grapples with a new revelation.

Meanwhile, the police connect Tom to more murder victims, and news of Tom and Beth’s unconventional sexual history quickly spreads across town, forcing them to address the fallout publicly.

Beth and Adam develop a plan, but a chase ensues which ends with a car crashing into the sea – however, when the vehicle is retrieved, there’s nobody inside…

Episode 4: As the shocking drama speeds to a gripping conclusion, a year has passed since the car crash, and Beth is making a new start. But her happiness is short lived as she uncovers evidence of who the true serial killer is.

With this damning new evidence Beth teams up with the police to capture the serial killer. But will she finally succeed in regaining control of her life…?
