An erotic film about the complex relationship between a man and a woman who meet through complicated family ties, including a brother-in-law and a sister-in-law.
Nam-gil and Woo-jin are enjoying fishing by the beach while drinking makgeolli (Korean rice wine) when they come across Gyeong-mi, a doll-like beauty who stands out in the rural setting. Later, Nam-gil returns home to grab some snacks only to discover that Gyeong-mi is in fact his sister-in-law, who has just returned from living abroad due to personal reasons. He offers her a massage to help relieve her fatigue from travel, which ignites a spark between the two. Meanwhile, Nam-gil’s wife, Seon-mi, who has their own complicated family history, bursts into anger after seeing her sister Gyeong-mi and leaves their house. She ends up drinking with her husband’s friend, Woo-jin, who had been enjoying the fishing at that moment.
