Dieter Roth was an artist who combined art and life in a unique way. He painted, drew, printed, wrote, filmed and made music. He created his own universe in which he turned all materials, no matter how banal or ephemeral, into art. The film "Dieter Roth" is conceived as an inner and outer journey, just as Dieter Roth lived, worked, taught, learned, loved and suffered while traveling. The starting point is his works, including videos and films in which he himself acts - friends and companions will also accompany this cinematic journey, above all his son Björn, who has worked with him for the last 20 years.
