Jae-sung, an aspiring actor who has hit rock bottom, prepares to commit a suicide. After his landlady insults him, he first cleans himself first at a public sauna. Hyung-wook, a notorious assassin, cleans himself at the same sauna after killing a target. Hyung-wook slips on a soap Jae-sung accidentally drops and passes out. Remembering Hyung-wook's luxurious look, Jae-sung switches his locker key with Hyung-wook's and steals his car and money. Feeling guilty, Jae-sung later tries to return everything to Hyung-wook, who is recuperating in the emergency room. When Jae-sung finds that Hyung-wook does not remember anything due to a concussion, he leaves without telling Hyung-wook anything.
