I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Lost Boys II: The Tribe Movie plot: Chris Emerson (Tad Hilgenbrink) and his sister Nicole (Autumn Reeser), children of Michael Emerson (from the first The Lost Boys movie) have moved to the surfside town of Luna Bay, California following the death of their parents. They rent a house from their Aunt Jillian (Gabrielle Rose), and Chris sets out to find a job as a surfboard shaper.

Later, as he's watching the sun set over the ocean, he is approached by Shane Powers (Angus Sutherland), who Chris recognizes as "the greatest surfer in the world," but who just up and disappeared. Shane invites Chris to a surfer party. At first, Chris doesn't want to go, but Nicole talks him into it. Neither Chris nor Nicole know that Shane is a vampire.At the party, while Chris is in the shower with Lisa Thompson (Moneca Delain), Nicole links up with Shane. Shane tricks her into drinking some of his blood from his hipflask and then takes her for a motorcycle ride.

On the way home, as Chris reads the riot act to Nicole, she suddenly starts feeling sick. He helps her into the house, telling her that she's probably just drunk. Nicole grabs him by the throat, hoists him up into the air, and says, "I'm not drunk." Suddenly, she is hit on the back of the head, drops Chris, and falls to the floor. Edgar Frog introduces himself as "surfboard shaper and vampire hunter." Chris takes a swing at Edgar, and when Edgar tells him that his sister is one of the undead, Chris kicks him out of the house.Just after kicking out Edgar, Chris hears a knock on the door. Thinking Edgar has returned, Chris opens the door angrily and sees Lisa standing there. She takes off her clothes and asks him to invite her in so that they can finish what they started in the shower. Once inside, she jumps all over him, so much that he fights her off, causing her to...
