Place from the Joseon Period, three musketeers struggle a powerful group who tries to overturn the imperial family and gain total power. The first choice of the Beautiful Three Musketeers is Jin-Ok (Ha Ji-Won), a smart and righteous female. Hong-Dan (Gang Ye-Won) could be the only married woman on the list of 3 women. Ga-Bi (Son Ga-In) could be the cutest one of the musketeers and excels at fighting.
