The atmospheric series adapted by Eli Roth ("Hostel") and writer Brian McGreevy from McGreevy's horror novel of the same name opens its first season with 17-year-old gypsy Peter Rumancek (Landon Liboiron) coming under suspicion for a grisly death shortly after he and his mother (Lili Taylor) arrive in the once-thriving Pennsylvania steel town of Hemlock Grove. That's due primarily to the musings of young Christina (Freya Tingley), a wannabe novelist who spreads a rumor that he's a werewolf after she observes him outside of his trailer home. Despite--or, perhaps, in spite of--what others think, however, fellow classmate Roman Godfrey (Bill Skarsgård), the scion of the region's richest family, befriends Peter; and, after another slaying, they join forces to find the real killer. Roman also deals with an eccentric, demanding mother (Famke Janssen), a freakish but sweet sister (Nicole Boivin) and a cousin (Penelope Mitchell) who believes an angel impregnated her. And, as the season progresses, the town sheriff (Aaron Douglas) is aided with his investigation into the deaths by a Department of Wildlife agent (Kandyse McClure) who may be more than what she seems.
