The Ex-Wife is a gripping drama about a woman who seemingly has the perfect life, except for the fact her husband's former spouse is always hanging around.

The official synopsis teases: "Newly married Tasha is living the dream: she has a beautiful London home, a loving and successful husband in Jack, and a gorgeous little girl, Emily. Everything would be perfect if only her husband's ex-wife Jen would leave them alone.

"Jen calls constantly and has close ties to Jack's family which is making life incredibly uncomfortable for Tasha. After a series of increasingly intrusive encounters, Tasha begins to think Jen might be trying to manipulate her way back into Jack’s life - but is Tasha just being paranoid?"

Things escalate when Jack and Emily disappear without a trace, and Tasha is forced to get to the bottom of what's going on, even begrudgingly asking Jen for help.

The series is based on the bestselling novel by Jess Ryder and has a cast of great British names who are bringing these characters to life across four episodes.
