While fleeing the police after serving a bad meal to an ambassador, chef Bong-hwan falls into a pool and wakes up in the body of a bygone queen.

Desperate to return to his own body, a disoriented Bong-hwan deflects King Cheoljong's sexual advances and starts flirting with a concubine.

Bong-hwan prepares a meal as So-yong and wins over the Grand Queen Dowager with modern cuisine; the king grows wary of the queen's odd behaviour.

So-yong is furious to realise it is Cheoljong who is trying to kill her. Later, the court maid of Hwa Jin goes missing and Cheoljong suspects So-yong is behind this incident.

After easing tensions with the king by halting the execution of Jo Hwa-jin, Bong-hwan devises a plan to return to his own body.

The king dismisses a case brought before the royal court to depose the queen for erratic behaviour; Queen Dowager Jo learns a shocking truth.
