A young prostitute may hold the key to bringing down a vicious serial killer in the second trailer for The Frozen Ground. Nicolas Cage stars as Alaskan detective Glen Flothe, who has been chasing this elusive murderer for years, when he catches a break. Vanessa Hudgens plays Cindy Paulson, who managed to escape from this maniac's clutches, and identifies Robert Hansen (John Cusack) as the man they've been looking for. Vanessa Hudgens herself introduces this video from writer-director Scott Walker's drama, debuting in theaters and on VOD August 23.
