When his best friend moves away, Artemis C. Funkleman, better known as Arte ( Ar-tee), sees no reason to attend fifth grade or to ever go to school again. Things only get worse when the new kid in class decides to make his life miserable. Fortunately, Arte’s newest friend, a one-eyed alien named boB, who lives mostly in Arte’s head but also in his room, comes up with a plan. Unfortunately, it’s a plan that only gets Arte into a whole lot more trouble.
