Max and Sebastian are great friends. Both are passionate cyclists, and live in an orphanage in Hamburg. But Sebastian suddenly gets new foster parents – in Berlin! Since Max can’t take it alone in the home, he runs away and hitches off to Berlin on his own. There he meets Juli, a Labrador whose master has just died. For Max and July it is the beginning of a wonderful, endless friendship. From now on they fight their way through together and look for a new home.
