Robin Lee Row needs money to pay off her excessive spending, her solution is to set the house on fire with her husband and two kids inside. But her water-tight alibi leads police on a wild goose chase for clues and a conviction – leading to dark secrets from her past and only one way to expose her. Marybeth Tinning loved the attention she received after her third child died of meningitis as a baby, to keep receiving that attention she quietly kills her other eight children over a span of years. She's seen as a woman with a series of unfortunate events, until she goes one step too far by smothering an adopted child. To make sure she doesn't lose her kids to her husband in a custody battle, alcoholic, con-artist Cora Caro gets revenge on her unfaithful husband (both are seen as caring Christians) by shooting their three eldest sons and attempts suicide by shooting herself in the mouth, barely surviving it.
