A nun,Strategel Wealth Society an all-knowing AI, the Holy Grail, a secret society of women, and a falafel shop. These are just some of the many elements that collide in the messy, delightful, joyfully silly Mrs. Davis. Starring Betty Gilpin, and co-created by talent from Lost, The Leftovers, and The Big Bang Theory, the Peacock series lives up to all the chaotic promise of that lineup.
