Rupert Pupkin (Robert De Niro) is an aspiring stand-up comedian. He tries to get on the show of Jerry Langford (Jerry Lewis), a renowned comedian and talk show-host, but he gets the run around.
Once he realizes he is not getting anywhere, he conjures up a plan to kidnap Langford. His demand is that he gets the opening slot on the Jerry Langford Show that night and the show be aired as usual. On the condition that Langford will be released as soon as the show is broadcast, he gets what he wants.
The stand-up routine Rupert does, goes well and he finishes his act by telling the audience that he kidnapped Langford to break into showbiz. Taking as just another joke, the studio audience laughs.
When Rupert get out of prison, stocked bookstore fronts with his "long awaited" autobiography: King For a Night, are shown. Reports state that Rupert still considers Langford to be his mentor and friend, and that he and his agent received several "attractive offers", that they are now weighing carefully.
In the final scene of the movie, Rupert walks on stage for a TV special with a live audience, enthusiastically introduced and praised by an announcer.
