In 1977 a group of young, horny, out of control Christians are spending a fun filled weekend at the Happy Day Bible Camp. Their impure antics rile up a sadistic crazy nun known as, "Sister Mary Chopper". One by one these youthful sinners pay a BLOODY penance for their sinful acts. 7 years later, another group of Bible totin' Christian wannabes return to the Happy Day Bible Camp. All ignore the warnings from the local folk of the grizzly murders that took place 7 years prior. Is Sister Mary Chopper dead or is she just waiting for backsliding Christians to commit sins of the unholy?

Sawdust in the Blood used to be a Carny compliment...not a description of a crime scene. There are a thousand sideshows playing thousands of small towns in 1936 when the Knuckles Brothers Show rolls into yet another town, ready to delight and dazzle the town folk with amazing acts and puzzling oddities. As they set up their tents they could not know that within days several of them would be dead, ripped savagely apart by a seemingly inhuman force, their souls stolen from their limp and bloody bodies. Step up, step up, ladies and gentlemen, the show is about to begin...
