简介：The Lakecrest College swim team is determined to win at all costs, even if it means taking steroids. But winning comes at a horrifying cost when harmless LEECHES in the campus lake, quietly feeding on the steroid-rich blood of the team's swimmers, mutate into giant parasites with a vicious streak. No one is safe as these ferocious creatures brutally stalk the students and staff of the rural college and literally bleed them dry.
