 Locals are celebrating the last night of carnival, such as newly in-love couple Bob and Kathy, coach, Neil Marshall, waitresses, timid blonde Lily and comely, nubile Ramona, their boss Jackson and learning difficulties teenage peeping tom Casey who s dad Avery is the town sheriff. Several them decide to spend the night down at the river, where a unknown double homicide climaxed there some nights before. But among the fairgoers is the one responsible for the deaths and as he/she lurks in the shadow troubled over a tragic past (or just about one thing or another) deciding to take his/her frustrations out with a machete on those he/she blames for all the misfortunes in his/her life. Following the group back to his/her riverside stamping grounds he/she sets about ensuring no one leaves the area alive.
