From IMDB:

Life for Dee Stanton is improving at every turn. Her legal career is blossoming and her boyfriend Dominic unexpectedly proposes to her. Things were very different 11 years ago when her husband Paul was jailed for the brutal murders of four girls and Dee was hounded from her home. Dee has kept all this a secret from her 15-year-old son Jamie. Now he has discovered the truth about his father and demands to see him.

From Acorn TV:

Dee Stanton (Jemma Redgrave, Holby City) seems to have a perfect life, with a blossoming career and a handsome fiance (Robson Green, Grantchester). But Dee’s tragic past comes back to haunt her when her son learns his father is a convicted serial killer. After a girl’s murder, Dee fears history is repeating itself. This gripping psychological thriller also stars Tara Fitzgerald (Game of Thrones).

From Acorn TV you can stream the 2 episodes of this British TV drama. Each episode is about 68 minutes long.

When you have such British actors as Jemma Redgrave (who plays Dee Stanton), Robson Green (who plays Dominic) and Phil Davis (who plays the imprisoned father serial killer), you know you are in for a treat.  Although the plot is somewhat like a soap opera, the tension and threat of a wrongful arrest are so strong that it is a blessing that there are only two episodes. Moreover, I would be surprised if you get to the near end and have correctly identified the killer.

For plot surprises and good acting let’s call this a DO NOT MISS!
