Lewis and Clark, aka The Sunshine Boys, were famous comedians during the vaudeville era, but off-stage they couldn't stand each other and haven't spoken in over 20 years of retirement. Willy Clark's nephew is the producer of a TV variety show that wants to feature a reunion of this classic duo. It is up to him to try to get the Sunshine Boys back together again.
