After his successful adaptation of Faust, Flix once again delivers a charmingly comedic blend of classic literature and pop culture, slapstick and tragedy. The quirky old Don Quixote battles against the establishment of a wind (mill) farm and genuinely believes the investors' representatives are marauding knights. Gradually, the reader realizes that Don is losing touch with reality and is suffering from Alzheimer's. Only his grandson Robin accepts him as he is. He also considers himself a knight, Batman - the Dark Knight.
