One night, Caleb Colton (Adrian Pasdar), a young man in a small town, meets an attractive young drifter named Mae (Jenny Wright). Just before sunrise, she bites him on the neck and runs off. The rising sun causes Caleb's flesh to smoke and burn. Mae arrives with a group of roaming vampires in an RV and takes him away. The most psychotic of the vampires, Severen (Bill Paxton), wants to kill Caleb but Mae reveals that she has already turned him. Their charismatic leader Jesse Hooker (Lance Henriksen) reluctantly agrees to allow Caleb to remain with them for a week, to see if he can learn to hunt and gain the group's trust. Caleb is unwilling to kill to feed, which alienates him from the others. To protect him, Mae kills for him and then has him drink from her wrist.
