Pepe (Cantinflas) is a hired hand, employed on a ranch. A boozing Hollywood director, Mr. Holt, buys a white stallion that belongs to Pepe's boss. Pepe, determined to get the horse back (as he considers it his family), decides to go to Hollywood. There he meets film stars, including Jimmy Durante, Frank Sinatra, Zsa Zsa Gabor, Bing Crosby, Maurice Chevalier and Jack Lemmon in drag as Daphne from ''Some Like It Hot''. He is also surprised by things that were new in the U.S. at the time, such as automatic doors. When he finally reaches the man who bought the horse, he is led to believe there is no hope of getting it back. However Mr. Holt offers him a job when he realizes that Pepe brings new life to the stallion. With his luck changing, Pepe wins big money in Las Vegas, enough that Mr. Hold lets him be the producer of his next movie. Most of the movie centers around his meeting Suzie Murphy (Shirley Jones), an actress on hard times who hates the world. Just like with the stallion, Pepe brings out the best in Suzie and helps her become a big star in a movie made by Mr. Holt. The last scene shows both him and the stallion back at the ranch with several foals.
