Part One: The Present Unravels

Elsie Mabel Fitzpatrick, an 81-year-old woman living on Kenny Lane in Melbourne, enjoys tea with her best friend Daphne when she discovers a threatening note: a photocopy of an old news article about her past. Elsie insists her story is really a love story about platonic female friendship. Her quiet life is further disrupted when seven-year-old neighbor Persephone, determined to interview an elderly person for homework, leads Elsie to discover their neighbor Ishaan dead on his kitchen floor. Suspicion immediately falls on Elsie, especially after Joan Waters publicly accuses her of murder. The police arrive, and Elsie’s bloodstained shoe becomes evidence.

YouTube journalists Adeem Anand and Libby Conquest arrive at Elsie’s home, identifying her as Mabel Waller, a convicted murderer. A water-pistol attack by protesters leaves Elsie hospitalized with a fractured wrist. During her recovery, Persephone visits and insists on signing her cast. Roxanne, Persephone’s mother, eventually asks Elsie directly if she is Mad Mabel; Elsie admits the truth, and Roxanne forbids Persephone from visiting. Yet Persephone defies her mother, climbing through Elsie’s bedroom window to maintain their bond.

Elsie agrees to a recorded interview with Libby and Adeem, hoping to control her narrative. Over several sessions, she recounts her childhood, her sister Kitty’s death from polio, her mother’s suicide, and her father’s cruelty. She admits to murdering her father but insists her aunt Cess’s death was his doing. Libby and Adeem eventually reveal that Daphne—Elsie’s lifelong best friend—is an imaginary friend Elsie created to survive trauma. They offer their own friendship, which Elsie tentatively accepts.

Part Two: The Past Revealed

In flashbacks, young Mabel Waller grows up at Rosehill, a beautiful estate her father loves more than his family. She endures relentless bullying at school, earning the nickname “Mad Mabel.” Her father spreads rumors that she deliberately gave polio to her baby sister Kitty, who died. After her mother jumps to her death upon learning of her father’s affair with Susan McGinty, Mabel is left isolated.

Aunt Cess and her friend Ness become Mabel’s guardians. Cess and Ness share a hidden romantic relationship, which Mabel discovers when she finds them in bed together. At school, teacher Mr. Loukas takes an interest in Mabel, grooming her into a secret relationship. He declares his love, words Mabel has never heard and becomes addicted to. When she visits his home, his fiancée Tessa confronts her, revealing Mr. Loukas has a history with other students.

Mr. Loukas dies in a car accident—later ruled homicide. Tessa confesses to the murder, but Mabel’s father continues spreading rumors. Mabel’s friendship with Christos deepens, though his mother bans him from seeing her due to her reputation. Billy Harris sexually assaults Mabel in a school bathroom; later, she pushes him in self-defense, causing him to fall and hit his head.

Cess fights to keep Rosehill, armed with her parents’ will. Mabel’s father threatens violence. One rainy day, Mabel returns home to find Cess dead with a broken neck and her father standing over her. Enraged, Mabel attacks him with an umbrella, stabbing and beating him until he dies. She covers Cess in a blue silk bathrobe and arranges her head on a pillow before saying goodbye to Daphne.

Part Three: The Aftermath

Back in the present, the documentary Magnificent Mabel goes viral, attracting 7.5 million views in a week. Public opinion reverses: a hand-painted sign reads “NOTHING MAD ABOUT MABEL,” and a sky banner appears with “FORGIVE US, MABEL.” Elsie is exonerated in Ishaan’s death after toxicology reveals a lethal vitamin overdose.

Elsie’s house is vandalized with the word “MAD” in blood-red paint. She decides to sell and move to protect Persephone and Roxanne. Peter, the neighbor she has long cared for, reveals he knows she is his biological mother—Elsie gave birth to him at age 15 while institutionalized. He was adopted by Ness and raised among war widows.

Shane, Roxanne’s abusive ex-husband, breaks into Roxanne’s home holding Persephone at gunpoint. Elsie lunges in front of the child and is shot. She dies hearing the voices of her loved ones: Joan, Roxanne, Peter, and Persephone. Three months later, Persephone tells her friend Daisy that Elsa has died. She still cries daily but takes comfort that Elsa left money to Peter, who shared it with their family. Daisy reveals she also knew Elsa, who called her Daphne.
