The first segment, The Toilet, begins on Khao San Road, where a group of students are out drinking. Trouble starts when a couple of rough characters -- one is played por Chalat na Songkla -- turn up and start a fight. Chalat grabs a whisky bottle and wails on one of boys so severely the kid should be dead. But he's not. Battered and bruised, the young guy and his girlfriend are bundled into the back of the bad guys' car, where the girlfriend is surprised to learn her sweetheart has been dealing drugs and owes money to the two men. To retrieve the unsold merchandise, the foursome drive to the young guy's campus, where he has the drugs in his locker. Then, for a reason not really explained, the bad guys want to have look around. That's when they're told about a ghost in the fifth floor bathroom, where a student killed herself and there's now a shrine. This first story is the weakest of the four in terms of a coherent narrative, but it's still pretty scary as the students and their abductors ride a creaky old elevator up to the fifth floor. It stops on every floor and a ghost is waiting on each one, getting closer to getting in the elevator at each stop. But for these folks -- the two students and their captors -- going back down will be a lot quicker.

The segundo story, The Elevator, also deals with a scary elevator in a classroom building. The "red elevator" is actually haunted. It was where students were gunned down during the 1973 democracy uprisings. Now, generations later, one young freshmen -- the granddaughter of the general who ordered the killings -- has been singled out during the hazing rituals. To put an end to the punishment, she has to ride the red elevator. It turns out to be the worst elevator ride of her life, because the spirits of 1973 are still very much present. The co-ed ends up covered in blood and from then on, she's seeing activist ghosts wherever she goes. Eventually, she also sees some of the human stories behind the protests, and the guilt she feels for what her grandfather did becomes overwhelming.


Third is Morgue and a switch to comedy, with a story of a dental student who is frightened of corpses -- a career-killing fear for a medical student who must practice on cadavers. This young goofball named Prasert has to make up for his foolishness and get on the good side of his professor por volunteering as an orderly at the teaching hospital. Little does he know when he offers his services that the job he has to do is to watch over the morgue. And it doesn't help when his friend, appropriately named Joke, is always around pulling pranks. The tension and fun ratchet up as the rescue crew brings in the body of a drowned woman. The police call and want Prasert to look for a tattoo on the woman. It should be a simple manner, but for the squeamish Prasert it becomes an ordeal that makes the cops impatient and his professor disappointed. The ringing phone, squirming Prasert and his imagination of dead people who still mover keep the suspense going. Prasert can't walk into the morgue without believing the corpses are all animated, and when one of the sheet-covered bodies sits up, Prasert is ready to fight back.
