풍운의 궁전(1957) / The Palace of Ambition (Pung-un-ui gungjeon)

A crown prince falls for a woman before the bride-selection ceremony without realising she is one of the two candidates, and a rival lord frames her father for treason to seat his own daughter instead. Jeong Chang-hwa answers the palace scheming with a disguise, a bandit ally and a raid on the throne room.
