He was one of the greatest geniuses that ever lived, a scholar - he had a brilliant mind, spoke thirty languages, knew physics and philosophy… and yet he slept on a park bench, had no real home, anonymously travelled the world and looked like a bum. He was the secret master of Nobel Prize Winner Elie Wiesel, of the great French philosopher Emmanuel Levinas and of many other prominent thinkers. They only knew him by his nickname “Shoshani”.

In Israel, France, Switzerland, USA, North-Africa, Uruguay, he was teaching and sharing his fountain of knowledge to all. They were left wondering: Who was this man? What was his name? Where is he coming from? Was he an angel or maybe a devil? How is it possible to know by heart thousands of books? What and why was he hiding? Still, to this day, no one knows.

The film explores the enigmatic life and knowledge of Mr. Shoshani, "The Wanderer who Knew it all", leaving many questions unanswered, making him one of the most mysterious figures of all time.
