A vengeful monster. An unsuspecting small town. Two men willing to sacrifice everything to save those they love.
Cody and Demetrius's quiet days of marital bliss are disrupted by the surprise arrival of Cody's teenage niece, Summer, and the continually strange behavior of Demetrius's Aunt Amelia. As the two juggle family drama and critter catching, they learn a number of people around Parson's Hollow have either been bitten by a mysterious large dog or gone missing, while others have been brutally attacked, including one of their clients.
Sheriff's Deputy Lucia Durant, refusing to entertain any notion of paranormal involvement, questions them mercilessly before calling in a State Police sergeant for assistance. As the evidence the Critter Catchers uncover points to a werewolf hiding in plain sight somewhere in town, Cody and Demetrius must try to convince Lucia and the mayor the truth about what is happening, and what it could mean if those bitten were to leave town.
When Cody's obnoxious brother Roman shows up unannounced to take Summer back home, the attacks take an even more personal twist, and Cody and Demetrius race against the clock, narrowing down their suspect list and counting down the days until the next, possibly fatal, full moon.
