Luck Key

Plot

Jae-sung (Lee Joon), an aspiring actor who hit rock bottom, wants to commit a suicide but decides to clean himself first at a public sauna. Hyung-wook (Yoo Hae-jin), a notorious assassin, just killed a man and tries to clean himself at the same sauna. Hyung-wook slips on a soap Jae-sung accidentally dropped 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 was in the emergency room but finds that Hyung-wook does not remember anything due to a concussion. He decides to leave without telling Hyung-wook anything. While Jae-sung enjoys Hyung-wook’s money and his fancy apartment, Hyung-wook struggles to find his identity. After Hyung-wook realizes that he is bankrupt, Lina (Jo Yoon-hee), who was a paramedic and paid emergency room bill for Hyung-wook, asks him to work at her mom's small restaurant so that he can pay her back. With his extreme knife skill, Hyung-wook becomes the main chef drawing many customers for the restaurant. He later finds a marked date on a calendar with a location information and learns that he (Jae-sung in reality) is an actor who is supposed to appear in a gangster-themed TV show as an extra. Hyung-wook excels in action scenes thanks to his real life skills and experience he does not know. His role in the show becomes more significant with Lina's help as the show progresses. Hyung-wook and Lina also find themselves liking each other. Meantime in Hyung-wook's apartment, Jae-sung discovers a secret room and thinks that Hyung-wook is an undercover cop protecting a witness named Eun-joo (Lim ji-yeon), who lives in the same building. Jae-sung tries to make up to her and they eventually fall in love with each other. One day, Jae-sung answers a phone call to Hyung-wook and meets with people who ask him why Eun-joo is still alive and when to kill her. Jae-sung realizes that Hyung-wook is actually an assassin hired to kill Eun-joo. After a picnic with Lina's family, Hyung-wook recovers his memory and finds Jae-sung and Eun-joo in his own apartment. Hyung-wook reveals to Jae-sung that he is not a real assassin and that he has been trying to give a new life to assassination victims by faking their death and sharing the money he makes. Hyung-wook, Jae-sung, and Eun-joo devise a new plan for themselves so that they can start a new clean life. Hyung-wook also tells Lina that they cannot be together and leaves. Heartbroken, Lina follows him to a place where Hyung-wook, Jae-sung, and Eun-joo are trying to fake their own death in front of the people who hired Hyung-wook. Lina's unexpected interference almost ruins the plan but they manage to succeed. People believe that they are all dead and leave. Later, Hyung-wook tells Lina who he really is and apologizes. Lina, not sure what to do, takes him to the set of the TV show to finish the final scene. On the set, Hyung-wook goes against a script and confesses his feeling to Lina who accepts it. At the final scene, Jae-sung and Hyung-wook are starting a fight in a new TV show.
