Luck-Key plot and story overview
At its core, Luck-Key follows a story that unfolds like this: 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.
Rather than rushing, the film lets tension build naturally, trusting the audience to keep up. The tagline — "A HIT MAN WAKES UP WITH AMNESIA TO A SWITCHED LIFE." — captures that tone perfectly. For a frame-by-frame breakdown, the dedicated Wikipedia entry and IMDb trivia pages are excellent companions.
