When Arnie and their cousin Paul run into trouble while fishing, the only hope of saving them is from Franz and a Canadian Coast Guard hovercraft. Robert, Arnie and Paul, all go fishing. Their boat has engine trouble and Paul, who is not watching drives the boat over a log breaking off the rudder and putting a hole in the hull. Unable to control the boat, they drift into the Skookumchuck (rapids). The Coast Guard Hovercraft comes to their rescue.
