A beautiful actress (Ko Shibasaki of 47 Ronin and Battle Royale) plays the protagonist in a new play based on a legendary ghost story. She pulls some strings to get her lover cast in the play, although he's a relatively unknown actor. With the cast in place, rehearsals for the play, about an abusive relationship and a grudge, begin. But off stage, some begin to develop their own obsessions. Trapped between the play and reality, they are horrified to find that a real grudge can cross the blurred line between reality and fantasy. Will love flourish? Or has it already turned hideously dark?
