Arthur Moffatt died of hypothermia in the afternoon of 14 September 1955, after his canoe capsized in rapids on the Dubawnt River in what is now Nunavut. Accusations of him began in 1959 and continued to 2014. The result was that much of the paddling community, and likely also members of the general public, became convinced that he died due to his incompetence.

The book presents extensive evidence expressed by the fellow paddlers on this trip, and other critical sources from journals, manuscripts, and archives in order to refute the claim that Moffat was incompetent and to prove that this was a paddling accident.
