You have probably heard of the phrase “to think outside the box”? Well, this is a film about such a box and the flat-headed creatures that live inside of it. Life in the Box is boring and miserable. Until one day a new baby boy starts to grow in the middle of the Box! This boy is very different from other flat-headed inhabitants of the Box. He’s happy, lively and curious. As the boy grows bigger and bigger, the flat-headed neighbours are becoming more and more annoyed with him. Until one day when he literally grows over their heads.
