Chicago Typewriter, A Likeable KDrama

So Chicago Typewriter is actually a nick name of a gun. Firing from the Thompson Submachine gun used in ’30s sounded like punching the typewriter keyboard hence it was called so. This interesting trivia you learn as the leads here are using this gun. The drama is a story of three freedom fighters during Japanese occupation of South Korea(around 1945), two of which get reincarnated after their death in the freedom fight while one becomes a ghost.
