4bia or Phobia (Thai: สี่แพร่ง or See Prang) is a Horror Anthology. The first segment, “Happiness” is about a lonely girl who corresponded with a stranger over hand phone text messaging and soon discovered something strange about this new stranger that she is attracted to. “Tit For Tat” spun a tale of black magic and vengeance for a school kid that had been bullied by a school gang. “In The Middle” – a group of friends faced one of their worst camping trip after water kayaking accident. The final segment “Last Fright” takes horror to new heights with a psychological thriller that involves a stewardess flying solo in a cabin with a dead body.

At a Thai hospital, a doctor and his seven nubile nurses engage in the sale of dead bodies. Jealousy causes one of the nurses to threaten to blow the whistle on the practice, so the others murder her. Soon the spirit of the slain nurse seeks revenge. In flashbacks we see the events leading up to the murder, and realize the full range of relationships between the main characters.
