The first arc, "Goatsucker", concerns a cryptid attack in Minnesota that appears to be the work of a Bigfoot-like creature. The plot also details the transfer of Ginger Brown, a young female agent, from the F.B.I to a secret organization called The Lodge. Once employed, Brown discovers that her partner is John "Proof" Prufrock, a Bigfoot who works in secret for the U.S. government. Brown's first case with The Lodge concerns El Chupacabra, a monster who masquerades as a human by wearing the skin of its victims. Ginger and Proof also encounter a number of cryptozoological fauna, including jackalopes, a golem, and the Cottingley Fairies. The second arc, "The Company of Men", follows Proof as he attempts to save a juvenile dinosaur from poachers in the Congo. The third arc is called "Thunderbirds Are Go!" and features dual main plots: Ginger and Elvis journey to New York City to find Joe the golem, while Proof investigates sightings of condorlike thunderbirds in rural Illinois. "Thunderbirds Are Go!" guest-stars The Savage Dragon, another Image Comics character. The fourth arc, "Julia," is set in the mid-19th century. The story delves into Proof's past with his so-called "brother" Mi-Chen Po, and the plot is loosely based on the history of Julia Pastrana. The fifth and final collection of the series entitled "Blue Fairies" gives readers a look at the maturation of male fairies, provides a brief look at the future of The Lodge, and concludes with the story "Who Killed the Dover Demon?" The final arc of the series sets the stage for the return of the character in a series of mini-series, the first of which is called Proof: Endangered.
