Though he is warned not to run past the old pendulum clock he does, of course, and slips into another dimension. He navigates through a number of adventures before stumbling upon the solution to returning. When he shows his new friend, Noelle, how to slip into the strange land, the two of them fearlessly explore. Then their younger siblings follow them through the portal and are captured. How will Tommy get the four of them safely back home?
