Once again, Al Quinn’s wish to lead a quiet life as a retired sheriff’s department detective gets interrupted. This time, a female con artist has ripped off a charity drive his brother, Maury, and his sister-in-law, Bonnie, are heading.

Sheriff Clayton also wants a favor. He asks Al to look into a report of a chupacabra, a mythological Texas beast that sucks the blood from goats. The tangled web causes Al and his “starting-to-get-serious” partner, Fergie, to cross paths with two hardened killers who decide Al and Fergie need to die.

Their dance across the drought-stricken countryside threatens to finish Al and Fergie, along with the rest of his household, including the baby, Little Al, and their dog, Tanner.
