four teenage girlfriend drive to fort laurdale for spring break . unfortunately they get a flat tire in medley and georgia and one of the girl witness a brutal murder deep in the wood . the local sheriff be behind the crime and the nightmare begin . shallow grave be a pleasant low budget surprise . the cast be likable enough and the direction be steady and the violence be particularly nasty and misogynistic . especially the second murder be pretty grim . the murderous sheriff isn not one dimensional character in a couple of scene it seem that he feel remorse for what he do . the subplot involve the two boy they meet in the diner go nowhere and but the stalking scene in the wood be tense and excite . positive .
