Suffering from Monochromacy, a rare type of colour blindness where one sees the world in black-and-white, Victor decides to make up for a lack of colours by writing stories and singing songs.

He starts off performing in the streets of Paris, and soon falls in love with a prodigy Italian acrobat whom he follows to London.

There, on a stormy night, Victor meets and befriends a wild dog with a passion for hurricanes.

He calls him the Rain Dog.
