Its two main participants, James Cooper and Henry Newton Brown, form a close friendship when, along with Billy the Kid, they fight in the Lincoln County War.

But something goes wrong, and in an emotive moment, the two best friends find themselves face to face in a dramatic and poignant confrontation.
