Jessie signs up for the Student Exchange program, hoping that he will be paired with a smart kid who he can copy off. But when Lars arrives from Outer Maledonia, Jessie realises that the echange isn't all that he hoped it would be when Lars takes over his room and turns out to be just as dumb as Jessie is. However things get even worse when Jessie learns that as part of the exchange he will have to spend time in the frozen wastelands of Outer Maledonia, where the only thing to eat is boiled fish and the sled dogs take an instant dislike to him. Meanwhile, Nancy, Penny and Sanjay sign up for Polly's Spoon School but soon find that they can't take the strain.
