Meet Wally and Dave. They're as opposite as two buddies can be. Wally (Richard Pryor) is brash, loud-mouthed and blind. Dave (Gene Wilder) is quiet, mild-mannered and deaf. Both of them are individual disaster zones. But together... they're even worse! When a murder takes place right under their noses, Wally and Dave are the only witnesses. The trouble is, Wally didn't see it and Dave didn't hear it, and all of a sudden they're both wanted for it! Suspected by the police and pursued by the real killers - the cool and calculated Eve (Joan Severance) and her fanatical henchman (Kevin Spacey) - Wally and Dave decide to take the law into their own hands. The results are hilarious! These guys are senseless, but they're certainly not stupid!
