Lassiter Hill chronicles the lives of two brothers competing with one another for everything, including the love of the same woman. Their private conflicts become public following a horrific murder that tears apart their small farming community. The bodies of two small children and their parents are discovered murdered in their beds, the day after Halloween. Evidence of a satanic cult is discovered at the murder scene, prompting the town residents to suspect immigrant workers at a nearby packing plant. A rookie prosecutor who attempts to unravel the murder mystery is handicapped by an incompetent sheriff and the towns suspicions of newcomers from a different cultural background. The forces culminate in a dramatic murder trial that garners statewide attention, pitting the prosecutor and his circumstantial evidence against the towns power elite and their preconceived attitudes.
