Mick Powers, wanted in Saint Paul, is living on the lam deep in the quiet woods of Wisconsin. Just after New Year's, his phone starts ringing with phantom calls. Then one snowy afternoon, a dark sedan lumbers down his driveway. Mick's dogs go into a frenzy of barking, trying to tell him that the visitors are big trouble. Out of that sedan pops Alvin Karpis, Fred Barker and his brother Doc. They say they only want a small favor. So begins an unwanted adventure that finds Mick involved in the final crime of the Barker Gang's long and deadly career.
