David is in the kitchen washing the dishes while his son Colin is playing with some empty boxes leftover from the move. David hears his son yell, "Daddy, come find me!" David, finishes cleaning the dish in his hands and then walks into the other room to find a couple boxes stacked on top of one another. "In here Daddy!" yells Colin. David walks over to the side of the boxes, kneels to the floor and crawls into a box, but as he begins to crawl, he realizes, the tunnel of boxes... it's not ending. He rounds a corner and finds himself in a much bigger box. "Come find me Daddy," David hears from far off in the distance. David is left with only a flashlight and box cutter, that he found on the floor of the box, to find his son and get out of this eerie place. But David isn't the only one trying to find his son. David must find his son before something else does, and he can only do that by thinking Outside The Box.
