The basis of the film is a series of original drawings with the joint title 'Upruption', drawn by Palle Nielsen from the autumn of 1965 to the beginning of 1966. There are people fleeing from a disaster which has already caught up with them, people thrown to the ground as if by a giant blow, crawling , cowering, always with their faces turned in terror to the sky, while entire cities crash around them. There is a mute, nameless horror around these faces that scream without sound. (DFI)
