Produced by Samuel L. Jackson and having him in the lead part. I guess Jackson really wanted to make this film.
He plays a once promising piano player who lost his mind and went to live in a cave in a park in New York. When he finds the body of a young man, he starts to investigate the murder, both aided and thwarted by his paranoid mind with its vision and inner voices.
Of course Jackson can play a mad man, but he also has to perform some drama which worked out less good. Even though the story is somewhat amusing at times, the obligatory unexpected plot twist towards the end is rather thin.
