The Teacher's Grace

The weak-bodied teacher Park (played by Woo Mi-hee) retreats to a secluded seaside after retirement. Her former student, Mi-zi (played by Seo Yeong-ji), who she took in a year ago, suggests holding a reunion to cheer the teacher up. The students who come to the reunion have strange behaviors: class president Si-ho (played by Yoo Hyun-soo), soon-to-be-married, along with vice president Eun-young, the curvaceous Soon-hee (played by Lee Ji-hyun), the limping Dae-bong, and the handsome Myung-ho, approach the teacher but harbor deep resentment because they have all been hurt by her in the past. Jung-yang, whose mother was hit by a car while confronting the teacher over him, appears unusually sarcastic. That night, after vehemently accusing the teacher of their grievances, one by one, the students are killed by a person wearing Jung-yang's clothes and a rabbit mask, with only teacher Park and Mi-zi, who desperately tries to protect her, surviving. When the police investigate, they discover that teacher Park never had a student named Mi-zi, and terror begins to unfold. Who's dark memories ruined everything? The truth is vastly different from what appears on the surface.
