Bites: The Werewolf Chronicles(2002)

"What's eating you?"

Overview

These are two of men who are cursed with lycanthropy. One, in Montreal, stalks his estranged sister, insisting that "The Beast" is telling him to kill her friends. And that she may be next. Then there's Jonas, whose astronaut father brought back a genetic inheritance from the moon, which might be affecting his now-adult son.
