They work for Limbo Corporation, a company dedicated to the shady business, whose CEO is Limboman. Vlak and Michele, his partner in vampire activities, reign supreme in the city. But Vlak has a restless spirit and decides to yank from his gums the fang chip through which he is monitored by Limboman. He has a mental blackout and starts to roam the city streets. Michele, searching for a new partner, meets Draco, a decadent vampire and former nemesis of Vlak. Their meeting encourages Draco to go back to the streets where he meets Daphne, a ripper psychopath who attacks her victims with a chainsaw. Draco joins her to find Vlak and avenge himself. Vlak, however, is abducted by Wang Su, a Chinese woman that is ruling the underworld in Rio. Wang Su wants to use Vlak to defeat Limboman and take over the command of the shady business.
