3-Iron (; lit. "Empty House") is a 2004 romantic drama film written, produced and directed by Kim Ki-duk. An international co-production between South Korea and Japan, the film stars Jae Hee as a young drifter who develops a relationship with an abused housewife (Lee Seung-yeon). The film's title is derived from a type of golf club used prominently throughout the narrative.


Tae-suk (Jae Hee) is a loner who drives around on his motorbike, taping takeout menus over the keyholes of front doors and breaking into apartments where the menus have not been removed. He lives in those apartments while their owners are away, washing their clothes, mending their broken appliances, and taking selfies with their possessions. When he breaks into one large home, he is unaware that he is being watched by an abused housewife and former model Sun-hwa (Lee Seung-yeon). Tae-suk leaves after making eye contact with Sun-hwa, but then returns. He witnesses Sun-hwa's husband Min-gyu abusing her and proceeds to catch his attention by practicing golf in the yard. He buffets Min-gyu with golf balls and then leaves with Sun-hwa.
