After years of selflessly supporting husband Dan (Christian Slater) during the early years of their marriage, when he was studying law and medicine, Betty Broderick (Amanda Peet) is understandably displeased when her successful hubby decides to dump her for a younger woman (Rachel Keller, "Legion"), in Season 2 of this anthology series. Soon, Betty strikes back against her errant ex in a series of increasingly deadly episodes. Tiera Skovbye ("Riverdale") plays Betty at a younger age.
