No, this is not a movie about killer clocks. Rather, it's about predatory wood ticks, mutated to monstrous size by herbal steroids dumped into the water by marijuana growers. Will an unsuspecting group of troubled big-city teens on a wilderness weekend be a match for the bloodthirsty critters? Rosalind Allen, Ami Dolenz, Peter Scolari, Seth Green, and Clint Howard star in this scary shocker that will make your skin crawl. 88 min. Widescreen; Soundtrack: English. Two-disc set.
