Ho-jin and Dae-jin were brothers. Elder brother Ho-jin married Eun-soo, and they lived together happily with Dae-jin. One day, both brothers get into accidents: Ho-jin dies while Dae-jin loses consciousness. Later, Dae-jin wakes up and claims that he is Ho-jin. Eun-soo is utterly confused as Dae-jin's behaviors are exactly like her husband's. She cannot believe such kind of spirit-transfer but she keeps noticing things about her husband from Dae-jin. Finally, Eun-soo accepts Dae-jin as her real husband. They begin a more passionate love, but the truth is far beyond one's imagination.
