Lassie makes her way upstream after helping rescue two campers who left their father to try out a new raft and were swept downstream on the rapids. Once she finds help, however, she must find the boys, who are also heading upstream. With Robert Patten, Don Eitner, Scott Perry, Robert Ferrel, and Danny Madrid. Note: When the question of who Lassie belongs to arises, the forest ranger replies, "Oh, I guess to everyone who needs her."
