In a tangled web of betrayal and revenge, Lucy's life comes to a brutal end, and four women emerge, each claiming to be her killer.

Lucy, in her thirties, lives with her nine-year-old daughter, Paige, from a previous marriage. Over the years, Lucy has wreaked havoc on the lives of four women: Jennifer, her best friend with whom she shares a tumultuous history; Clara, Lucy's estranged younger sister; Gillian, whose husband lost his job because of Lucy's manipulations; and Rosa, her ex-husband's new wife.

Each of these women harbours a deep-seated hatred for Lucy and possesses both the motive and means to kill her, but all four are claiming responsibility for her murder.

Who is truly to blame?

This is not your typical whodunnit; it’s a gripping who-didn’t-dunnit. Rosa, Jennifer, Clara, and Gillian recount their stories, each insisting on her role in Lucy's demise.
