This play is based on the life of John Merrick, a horribly deformed man who lived in London in the late 19th century. After being abandoned by the traveling freak show in which he had been exhibited, he was admitted to Whitechapel Hospital under the care of Dr. Frederick Treves. Merrick is given a permanent home in the hospital.

Treves educates him and introduces him to London society, including the famous actress, Mrs. Kendal. Merrick becomes quite the favorite of the "in" group. However, as he learns more about society and human nature, he realizes that he will never be accepted simply as an ordinary person. Eventually, he dies in his sleep, presumably because he tries to sleep lying down (like ordinary people do) and the size and position of his enormous head compresses his windpipe and he suffocates.
