Brian Robeson, a 13-year-old boy who spent 54 days surviving alone in the Canadian wilderness the previous summer, is hired by the government to again live in the woods and survive using only his wits so the military can learn his
survival techniques. Though reluctant at first, Brian eventually agrees. This time, Brian sets out for a remote Canadian location accompanied by Derek Holtzer, a government
psychologist. Though the government stipulated the duo take emergency supplies, Brian insists they abandon everything but a knife and an emergency
radio, saying that it would be impossible to eat bugs and sleep in the rain when a tent and prepared food is within reach. During their stay, things take a grim turn when their camp is struck by lightning, which knocks Derek into a
coma and destroys the radio. Knowing that Derek will die of
dehydration long before anyone finds them, Brian builds a
raft in a desperate bid to navigate down the unknown river to Brannock's Trading Post, the nearest inhabited point, for emergency aid. The biggest problem is the trading post is downriver. Despite rapids, the craft's unwieldiness, exhaustion, and a lack of geographical knowledge, they finally reach the trading post and Derek survives. After the two get back home, Derek buys Brian a
canoe named
The Raft as a thank you present. ==Reception==
