Salaryman Jin-Taek ends up living with his 20-year- old niece after a request from his sister-in-law. She looks so much like her mother that Jin-Taek, who's lived a life of discipline and restraint, finds himself slowly sinking into a swamp of desire. To make things worse, she keeps calling him "Dad"... and sneaks into his room every night.

"Dad, I want to do it with you."
