Walter Wanger (Jon Hamm) bets everything on a different Joan -- Joan of Arc, starring Ingrid Bergman -- and comes up short, as the actress playing the saint sparks an international sex scandal. With Walter’s fame and fortune seemingly running out, he becomes consumed with trying to make three adultery-themed films, which ironically draws his attentions away from his own family and marriage – causing a neglected Joan (Zooey Deschanel) to turn to her young agent for companionship.
