Stephanie Smothers, a suburban overachiever played by Anna Kendrick with spunky energy and self-effacing deflection, is the widowed mother of a son in elementary school. Into her life steps Emily Nelson (Blake Lively), a sleek urban professional with no maternal instincts––like a high- society shark forcibly moved from her hunting ground to a tranquil aquarium tank. Their odd relationship is the core of A Simple Favor, a neo-noir of suburban pep and middle-class warmth meeting cool sophistication. Playdates, cocktails, and dark secrets are shared.
