A boy faces his fear by facing the dark.

Once there was a boy who was afraid of the dark. One day, while playing on an abandoned factory's roof, he let a valuable belonging fall through a gap between the tiles. Going into the factory means facing his phobia and, inside, a beast's gaze awaits.

The moon that the boy sees was shot in Madrid.

Some of the shots of the boy down in the abandoned factory are 3 years apart.

The "father's watch" plot device was conceived during editing, forcing a re-shoot and the creation of several new animation sequences.

Each of the animations in the short where conceived in a different style and directed by a different person.
