Vampire hunter Edgar Frog is destitute and nearly friendless, when the beautiful novelist Gwen Lieber offers him a small fortune to go on a hunt to save her brother from vampires using a new drug called the Thirst, which is a mixture of Ecstasy and infected blood. Realising he can't do this alone, Edgar turns to his brother, Alan Frog, to help him save Gwen's brother.
