A rucksack flies over a wall. Shortly thereafter, a pale young man in a black suit climbs over the wall and runs off. It is the beginning of an extraordinary odyssey. Julian wants to heal his best friend’s fatherby walking the length of the country, from Berlin to southern Germany. On the way he meets Ju, a young doctor, who is struggling to come to terms with the death of a young patient. From one day to the next, she turns her back on her life and joins Julian on his journey. They couldn’t be more different: he’s a dreamer, she’s a pragmatic realistic. But she doesn’t want to be reasonable anymore.

They both then meet Ruth, who is supposed to be going on holiday with her husband and her children, but changes her mind. Now Julian has two companions, who both want to believe that the world consists of more than that little piece of reality in which they seem entrapped. But what Julian keeps secret from them is that he has broken out of a mental hospital. This brings Jan into play, a burnt-out, volatile police detective, who is supposed to bring Julian back to the mental hospital.

Through Jan, the two women discover that Julian caused a car accident, in which his best friend died, by attempting to mentally overcome the laws of gravity. Julian’s initial worry that the everyday concerns of his travelling companions could divert his attention from his goal lessens during the course of the journey. As he opens up to his new friends – especially toward Ju -, Julian is confronted with the question of what is more important: healing his best friend’s father or his love for Ju?
