That's the old wives' advice when passing a cemetery, lest you inhale spirits too evil for hell to retain. It seems that someone amongst a group of buddies heading for a camping trip didn't listen, and the malevolent ghost of a serial killer will make sure that they all stop breathing. Shocker stars Katrina Bowden, Randy Wayne, Lisa Younger, Seth Cassell. 90 min. Widescreen; Soundtrack: English Dolby Digital 5.1; featurette.
