Victims' rights activist John Walsh returns to weekly TV as host of a documentary-style investigation series. Walsh details stories of ongoing cases involving fugitives, with the intent of expanding searches outside the United States. Interviews with victims, loved ones and law enforcement accompany new leads in each hourlong episode, giving the public information to facilitate the capture of suspects. Walsh, a spokesman for the National Center for Missing & Exploited Children, hosted the series "America's Most Wanted" for 25 years, helping apprehend more than 1,200 criminals.
