Ahead of its series premiere "Summons", airing tonight at 10 PM ET on Syfy, the network has released a new trailer for Bitten. Laura Vandervoort stars as Elena, the only female werewolf in existence, who returns to her home of Stonehaven to defend the pack she once abandoned. Will you be tuning in tonight on Syfy after watching this new footage?

Based on the New York Times best-selling Women of the Otherworld novels by Kelley Armstrong, Bitten is an emotionally charged supernatural thriller starring Laura Vandervoort (Smallville, Ted) as Elena Michaels, the lone female werewolf in existence.

Desperate to escape both a world she never wanted to be part of and the man who turned her into a werewolf, Elena (Vandervoort) has abandoned her Pack and taken refuge in a new city. There, she works as a photographer and hides her werewolf existence from her new boyfriend. When bodies start turning up in her Pack's backyard, Elena finds herself back at Stonehaven, the werewolves' ancestral domain. Torn between two worlds and two loves, she quickly realizes that - when push comes to shove - she'll stop at nothing to defend her Pack.
