When teenagers begin mysteriously vanishing in Mexico, they find a rehab clinic run by Tesla, who is experimenting with a serum of his own design to bring back the vampire race over several decades. One of his patients, however, tweaks the process to make it faster and more effective, and he kidnaps Tesla to be the leader of the new race. The team break in to stop them, and Tesla uses his antidote to the serum to turn the vampires back to humans, accidentally transforming himself during the fight as well. At the end, Tesla’s new magnetic ability manifests itself.
