Dr. Xenon Pearl cuts brains for a living, and he's as good as it gets. His direct, sometimes abrasive style is forgivable in light of his skill with a scalpel, and tempered by his compassion for his patients and his friends. He is a dutiful son to his widower father, a doting grandchild to a grandfather who was once a rabbi, and he has even met the girl of his dreams. Everything is on-track for this medical golden boy. The other side of this motorcycle-riding, brilliant doctor facade is a side that Xenon (aka Zee) hides even from his father. Secretly trained since childhood by his Chinese nanny, Wu, Tie Mei--herself a martial warrior of shadowy lineage--Dr. Xenon Pearl is also a martial arts expert who loves the sword as much as the scalpel. Through Tie Mei's training of Zee, we see the philosophical and spiritual practice of a warrior, and how it guides his every step. Now his past is showing up to literally haunt him. His dead teacher reappears, reminding him of the warrior lives he has lived before, and demands he fulfill his destiny. Xenon must use his skill with a blade to protect the innocent, face down the Russian mob, protect the blade mistress who loves him, and stay one step ahead of a smart cop; he is set to lose everything unless he can cut just one more time.
