The Ex-Wife on Paramount Plus is a gripping British thriller that brings to life the bestselling novel by Jess Ryder (opens in new tab) about an ex-wife who is always hanging around.

Tasha, played by Céline Buckens, appears to have everything, from her loving husband Jack (Sleepy Hollow’s Tom Mison) and their beautiful daughter Emily to their gorgeous home and seemingly perfect life. The only problem is Jack’s ever-present ex-wife Jen, played by Janet Montgomery, calls him constantly and refuses to sever ties with his family. But when it all comes crashing down, Tasha is left with no choice but to turn to Jen, the woman she despises, for help. 

The novel has been adapted for the screen by Downton Abbey star Catherine Steadman, who is also a bestselling thriller writer herself, so it’s sure to be edge-of-your-seat stuff.
