The Ecstasy of Isabel Mann

Isabel Mann, a teenager, falls under the influence of a brutal group of vampires who can walk in daylight. As her fellow students begin to disappear, two detectives are drawn into the mystery. The situation becomes increasingly bizarre as Isabel, now unhinged, begins to murder freely in the surrounding forest. She receives support from Alejo, the leader of the vampires, and unsettlingly, from her long-lost mother, who was recruited by the vampires earlier. Isabel is taught the deadly skills of a killer, leading to gruesome consequences for those she cares about.
