John Howl is a young Los Angeles police detective out to find the killer of a young film star. As the charming but angst-ridden officer dives deeper into the case, he realizes Hollywood is a totally different world than the one he lives in- not that it's any more weird; after all, he's a werewolf by night! Though his work hours are hindered by the beast inside, Howl's journey through the mean streets of Hollywood is a blood quest for justice and towards his need to feed.
