Her Grandpa has a canoe, but there is no way he will let her use it. They decide to ignore her Grandpa and fix the canoe themselves. But somebody, or something, wants to stop them, because the hole is back again the next day. They fix it again and Jem joins the race. She quickly gets lost in the fog, and as the boat begins to sink, Jem finds that she is not alone...
