An adventurous foursome reach the Mckenzie mountains in the northwest Canada to follow the Matla and Keele river courses in the canoes. They do not intend to explore; they are just in search of adventure in the true sporting spirit. Since the journey is long and they must live side by side for many days, the close bond of friendship uniting these men is essential for the successful outcome of the venture. The film wishes to transmit this atmosphere in contact with nature that is practically still intact.
