Wally Karue (Richard Pryor) is a blind man looking for a job. Dave Lyons (Gene Wilder) is a deaf man who runs a newsstand. When Dave hires Wally, he never imagines they'll have to work together to survive. After a murder occurs at their newsstand, they figure out who the killer is with their collective senses -- but the investigating detective (Alan North) pegs them as the main suspects. When the real killer (Joan Severance) returns to cover her tracks, the two must really cooperate to live.
