Let It Snow

S5 E4: Christopher is barely 21, already has history of domestic abuse and assault, and now he's facing major time in a room without a view. This hunt won't be easy for Dog -- the leads are few, informers and family are not forthcoming, and the posse has to confront a freak April blizzard as well. Braving freezing temperatures, blowing snow, and treacherous highways, they hunt through the day and into the night. But as darkness draws close the leads are as cold as ice... until an unexpected call turns the trail red hot.
