Seina Kasugai

When Keung's girlfriend, Apple, goes on a business trip, he takes the opportunity to approach Yurei, their new next door neighbor who is a stewardess. Although she seems pleasant enough on the outside, Keung soon discovers to his horror that she is mentally disturbed, and is only pretending to be a stewardess. But when Keung attempts to find out the whole truth, and alert the authorities, Yurei lures him into a deadly game of cat and mouse that he may not survive. (imdb)
