A new group of kids has come to spend the weekend at Secret Valley. Among them is Jeff, a guy who seems to be incompetent at everything he does.

Spider McGlurk sprinkles flour over Secret Valley Camp and, for once, manages to escape in his minibike. Secret Valley kids are frustrated because it is the third time he has done it, and they can't chase him because his minibike is way too fast. Lofty has an idea to raise money, organize aSecret Valley mini bike race where "Spider" Mc Glurk will also compete.
