In 1987 a massive snowstorm hits New York as Peter Kaldheim flees the city, owing drug debts to a dealer who is no stranger to casual violence. Leaving behind his chaotic past, Kaldheim hits the road, living hand-to-mouth in flop-houses, pan-handling with his fellow itinerants. As he makes his way across America in search of a new life, the harsh reality of vagrancy forces him to face up to his past, from his time in Rikers prison, to relationships lost and lamented. Kaldheim hikes and buses through an America rarely seen, and his encounters with a disparate collection of characters instils in him a new empathy and wisdom, as he journeys on a road less travelled.
