An institutionalized man reads classic literature in his padded cell. He believes that he is a knight like in the books he reads and attacks a guard checking in on him. After escaping from the asylum, he happens upon a horse and makeshift suit of armor. With the police on his tail, he travels on until he encounters and fights a windmill that he believes to be a giant. Once the windmill is defeated, he moves on to the house of an opera singer whom he mistakes for a screaming damsel in distress. But before he can save the woman, he must battle a backhoe that he believes to be a dragon. When he finally reaches his damsel, he discovers that she is an ugly woman and both he and the guard pursuing him run back to the institution and lock themselves in the cell.
