However, a black shadow is following them, also wanting something to do with the sinister box.
The children are risking a lot more than skipping a few classes to find out what is going on, and soon they will know that their lives are at stake.
Young and naive, they were unaware of the impending doom they were throwing themselves into, and will learn they never should've gone near the evil box in the first place - the hard way.
