Mole lives in his den where everything is black and white except for his colorful friend who looks like a nightlight. Since he does not dare to go out, his friend describes the wonderful world that exists on the surface thanks to light and color. Mole is afraid to go out, so he tries to find the color by digging more holes from his cave, but to no avail. One day his friend disappears, and following the light that enters her cave, he decides to get out of the hole to marvel at what he discovers in the outside world.
