The show follows former attorney Michaela Kell (Julianne Moore) who is married to billionaire Peter Kell (Kevin Bacon) and works closely with her assistant Simone (Milly Alcock). Their lives become tense when Simone introduces the couple to her sister Devon (Meghann Fahy).

In the wake of Ethan (Glenn Howerton) drunkenly falling off a cliff while arguing with Simone about their breakup and the Vanity Fair photographer showing Michaela the photo of Peter kissing Simone, things really begin to spiral out of control for the younger DeWitt sister.
