A reverse comedy that tells the story of a perfectionist assassin who falls and hits his head in a sauna, giving him amnesia. When a down-and-out actor switches locker keys with him, they switch lives until the hit-man, who soon becomes an action hero on TV, starts to remember things.

Loosely remaking Kenji Uchida’s 2012 film Key of Life, Korean filmmaker Lee Gye-byeok forges a unique interpretation packed with bloody action. Yoo Hae-jin—best known for his gangster roles—gives a star-powered performance in this brilliantly funny comedy of mixed identities and lost memories.
