After serving in the military for 8 years, Seoyoon arrives home to find that not only has her father lost their family home, but they're now penniless. A friend tells her about a security position he describes as "hell"—were it not for the salary. In an attempt to regain some of what their family lost, Seoyoon decides to go to the Kingdom of Oman for one year to work as a member of Prince Ashal Al Lugerta's private security team. But the so-called polar bear of the desert keeps changing the rules, and Seoyoon's not sure she'll make it out anytime soon.
