Porky the jockey is getting his prize entry ready for the big steeplechase, but an overambitious and ever-confident, somewhat bumbling nag (who needs an owner) is determined to convince Porky to ride him in the race. The pony flimflams Porky into buying him. After a steady series of spastic attempts to impress Porky, the nag bumbles his way into being Porky's entry when Porky's horse gets drunk.
