For Her Sins is an exciting four-part psychological thriller in which successful lawyer Laura (ex-EastEnders star Jo Joyner), who has been struggling since becoming a mother to two young children, is relieved to make a new friend in Emily (Rachel Shenton) — but doesn't realize that her new pal is secretly plotting to cause trouble in her life.

Written by Jo Rogers and directed by Adrian McDowall, the series plots the gradual unraveling of Laura's seemingly perfect life as Emily embarks on her campaign to undermine Laura at every turn.

Jo Joyner explains: "Laura's at such a low ebb when we meet her, in her home life, and it's so out of character because she's used to being in control and in charge at work. What Emily does really well is find her at that point and then just pulls those little threads every now and then — gaslighting her, ultimately, pretending to be the best thing in her life at the moment. So it's a really complex relationship, and it's written really well, and one of the things I loved about it was how she chips away at Laura's confidence without Laura even knowing."

Here's everything we know about the series so far...

For Her Sins release date

What's the plot?

As a high-flying lawyer, Laura Conroy is used to being the one in control — but since becoming a mother to two young children, she's found herself losing her self-assurance, particularly with her husband Rob often away on business, leaving Laura to raise their children largely on her own.

When Laura loses sight of her daughter Eliza in the park one day, she finds her with Emily, a kindly stranger — and then the two meet again at the school gates when Emily steps in to save Laura from one of Eliza's tantrums.

Laura and Emily soon become firm friends, and Laura is relieved to finally have someone to talk to about her anxieties around motherhood — but what she doesn't realise is that she and Emily are connected by an event in their past, and Emily's arrival in her life was no accident...
