is making a gruesome splash on WonderCon weekend. In a video clip that premiered on
's character, Lynda Rumancek, looks on with frightening satisfaction as a handsome young man makes his slow and terrifying transformation into a werewolf.
The show, which
released its official poster
earlier this month, uses the tagline, "The monster is within." And based on this preview, it's not just a saying. After the dude's eyeballs pop out on to the ground to be replaced by beady wolf eyes, and after claws protrude from what used to be his human hands, the face of the beast emerges straight from his face as bloody human teeth hit the ground in piles. It almost makes you forget about what just happened to the guy's back ... Almost.
The premise of "Hemlock Grove" -- brought to you by
Eli Roth ("Grindhouse," "Hostel") and based on the novel by
Brian McGreevy -- is a murder mystery surrounding the brutal death of 17-year-old Brooke Bluebell. The investigation into Brooke's murder uncovers a seamy side of the former Pennsylvania steel town, wherein every person -- and creature -- is a suspect. The show promises to be graphic, and if this teaser is any indication, Roth will deliver on the promise.
"Hemlock Grove" will air exclusively on Netflix. All 13 episodes of Season 1 become available April 19. Will you be watching?
