See No Evil, Hear No Evil

Dave (Gene Wilder) is a deaf news-stand owner who hires Wally (Richard Pryor), a blind man, to work for him.

However, when Wally's bookie comes to collect some money that he is owed the bookie is murdered by a woman, leaving Wally and Dave as particularly bad witnesses to the shooting.

Unfortunately, the police begin to believe that the deaf and blind duo are the killers...
