Doc Carter, his lovely daughter Dolores, and preacher Dan Young have their hands full caring for the infirm. When one of the patients dies unexpectedly, Dan notices two puncture wounds on her neck. His investigation leads him to the strange gunslinger Drake Robey, who always seems to be slower on the draw than his opponents, but who—despite being outdrawn, and even shot—always manages to survive these deadly encounters. Dan soon discovers that Drake also has an aversion to crucifixes, sleeps in coffins, and cannot tolerate sunlight...
