Lost boys: the tribe: The orphan and former surfer Chris Emerson and his sister Nicole Emerson move to Luna Bay expecting to initiate a new life without housing expenses with their Aunt Jillian, but she charges rent to the siblings for a wrecked house, and Chris seeks a job working as board shaper to raise money for the unforeseeable expenses. While in town, he meets his acquaintance and also former surfer Shane Powers that invites Chris for a surf parting at night. Then the siblings unsuccessfully seek out the board shaper and vampire hunter Edgar Frog in his trailer trying to find a job and Chris leaves a message for him. They go to Shane's party and Nicole stays with Shane and drinks booze offered by him. Later she becomes a half-vampire and Edgar advises that she drank vampire's blood and can only be saved if the head-vampire is killed. Chris and Edgar search the hiding place of Shane and his tribe to save Nicole.

Lost boys: the thirst: In San Cazador, California, the clumsy vampire hunter Edgar Frog is evicted from his trailer. But the best-seller writer Gwen Lieber offers him a job to destroy the head vampire DJ X that promotes worldwide raves to increase his army of undead. Gwen tells that her brother Peter disappeared in Ibiza two years ago in an X-Party promoted by the alpha-vampire. Now DJ X is coming to San Cazador to promote a sacrifice during a party in the blood moon on the next Friday, and Edgar discovers that the rave will take place in a slaughterhouse on an island. Gwen hires also the Hollywood participant of reality show Lars von Goetz that comes with the cameraman Claus. Edgar invites his brother Alan to join the team but he declines, and he teams up with his friend Zoe. When the group finds DJ X, Edgar discloses a secret about the head-vampire.
