Everyone's favourite girl-next-door serial killer, Rhiannon Lewis, is back, and she's more unpredictable than ever...

Sometimes, you can be your own worst enemy...

Rhiannon Lewis thought she finally had it all: thanks to the pandemic she's had to keep a much lower profile but has found happiness with her fiance Rafael and his family. For once, she is surrounded by people who love her for who she is (or who they think she is).

After over 800 days without murdering anyone, the woman formerly known as the Sweetpea Killer thinks she might have finally turned over a new leaf.

That is until her soon-to-be sister-in-law has a run in with her abusive ex, and Rhiannon rediscovers her taste for revenge. This time, with a loving family in tow, the stakes are much higher. Wedded bliss and life as a normal person are finally within Rhiannon's reach, but you can never keep a good serial killer down.

Can you?
