While this is a series that may have been missed by many when it was first released on BritBox in 2021, it's now getting an ITVX release, meaning that plenty more thriller fans will be able to tuck into the twisted plot of the five-part series.

The drama follows Cush Jumbo (Deadwater Fell, Criminal Record) as a mother intent on avenging her son's death after he was tragically killed in a hit and run. She wishes for nothing more than to find the man responsible and kill him as her personal form of justice.

Jumbo isn't the only familiar face in this cast, as she is also joined by Billy Howle (Under the Banner of Heaven) as Detective Strangeways, who is investigating the case, as well as Jared Harris (Chernobyl) as "master manipulator" George Rattery.
