Steve's group is attacked by another pack of dogs at a camp of dilapidated cabins. Professor MacGregor and Roy are both killed by the dogs, as Steve, Terry and Daniel run off. The three hurry down to the nearby creek and push a raft into the water, but as they push off, the dogs leap onto the raft, forcing them overboard. The three hang onto the raft as a current catches it and pulls it downstream through the rapids, while the dogs on the raft eventually drown.
