Michael Herne is a gentle, unassuming librarian. When he is asked to play a king in a medieval play he reluctantly agrees. After the play is over, however, strange things begin to happen. Michael refuses to change back into his everyday clothes and other actors find it impossible to return to their real character.

Set in the early 20th Century, this is the intriguing story of the rise of a new Don Quixote who introduces a medieval government into the world of big business.
