A young martial artist has to survive the dangerous underground world of martial artists filled with grifters, demons and supernatural forces. What's a boy to do?

Quincy Zi doesn't mind battling ten-foot ogres or taking down other evil creatures of the Otherworld - as long as it's in a well-lit area, preferably during the daytime. As a member of the Secret Society of the Black Scabbards, Quincy is part of an elite group of underground martial artists, but he has one fatal flaw - he's deathly afraid of the dark.

To become a full-fledged member of the Black Scabbards, Quincy must pass the Apprentice Test and destroy a dangerous creature of the Otherworld. But as luck would have it, the creature only attacks children and the elderly at night. As Quincy embarks on his test, he discovers a terrible link between the creature and his mother's last mission before she died. Can Quincy get over his fears, pass his test and find answers to his past?
