Will and Magnus' investigation into the mysterious disappearances of privalaged young adults leads them to a rehab clinic in Mexico that is run by Tesla. He reveals he cured them with a serum that is meant to turn them into vampires in 30 years, thereby restoring the extinct species. However one of the patients (Chad Rook) learned the hard way that death also triggers the conversion; he then kills his friends from rehab to convert them as well. The group kidnap Tesla but quickly realize his aims are not as consistent as theirs. The Sanctuary team finds Tesla's failsafe, a "de-vamper", and break into the vampires' hideout. Tesla then uses the device to convert them back to human, but during the struggle accidentally targets himself and is also de-vamped. Tesla is very distressed at this development and can find no way to regain his vampire status. However he discovers he has gained a new power; magnetism.
