and Crandall head to Spider Lake, Wisconsin, on April 22, 1934, but barking dogs alert the gangsters and they scatter. The agents then head to a nearby country store to call the Chicago office. When they get there they find Baby Face Nelson (William Phipps) holding two men hostage. Nelson opens fire, fatally wounding Crandall. Hardesty then recounts his involvement in the capture and/or deaths of numerous infamous mobsters of the day including John Dillinger, Pretty Boy Floyd, Baby Face Nelson, and Machine Gun Kelly. Unable to get Chip to obey her to leave the bureau, Lucy decides to leave their marriage and take his children from him. They move into her parents' home. While preparing an Easter egg hunt, Lucy ironically calls her mother "a nag, a real nag." Later, Lucy's mother sarcastically tells Lucy that Lucy's father is also "a nag."
