Sick Nurses (Thai: สวยลากไส้ or Suay Laak Sai) is a 2007 Thai horror film, written and directed by Piraphan Laoyont and Thodsapol Siriwiwat.


In a run-down, suburban Bangkok hospital, young Dr. Tar (Wichan Jarujinda) and seven nurses have been running a scheme to sell dead bodies on the black market. However, one nurse, Tahwaan (Chol Wachananont), has found out that her boyfriend, Dr. Tar, has been having an affair with her sister, Nook (Chidjun Rujiphan). Growing tired of the body-selling scam and enraged by her sister and boyfriend's betrayal, Tahwaan threatens to call the police.

However, before Tahwaan can take action, the doctor and six resident nurses at the hospital strap Tahwaan to an operating table, kill her, and then wrap her in a black plastic garbage bag. They then dump her in the trunk of the doctor’s car, where her corpse will be kept on dry ice until it can be sold.

All the women have their own obsessions and weaknesses. The spirit of Tahwaan uses these obsessions to torment and ultimately kill the other six nurses. Scenes shown toward the end of the film indicate that many of these obsessions were in part encouraged by Dr. Tar, or in some cases, used by him to seduce some of the women. For example, Aeh (Kanya Rattanapetch) seems unhealthily attracted to material possession such as jewelry, dresses, and handbags. One brief scene shows Dr. Tar giving Aeh a handbag that was shown sewn to her head and neck earlier in such a manner that when Nook tries to undo the stitching, Aeh is left decapitated.

It is eventually revealed that Tahwaan was once a homosexual male who had undergone a sex change so that he could marry Dr. Tar. She finally kills her own sister by being literally reborn through her and as she stares at Tar, she mutters "marry me" and the screen goes black
