Jason, a curious and imaginative first-grader, starts noticing strange things about his teacher, Miss Jenkins. She never seems to blink, her movements are too precise, and she always knows the answers to every question-almost as if she's programmed. Convinced she might be a robot, he shares his theory with his best friend, Justin. Even though Justin doubts his mad spy skills and his theory in general, he agrees to follow his master plan to expose Miss Jenkins for the robot that she is. Will the boys expose her before it's too late and Miss Jenkins takes over the school?
