In a medieval kingdom, a reckless and arrogant prince becomes obsessed with a mysterious noblewoman he meets at a masquerade ball. Unbeknownst to him, she is actually a meticulous con artist and thief on a dangerous mission that requires her to repeatedly infiltrate the royal court and get close to him. While the prince hunts a notorious thief across the kingdom, he doesn’t realize the woman he trusts—and keeps “accidentally” meeting—is the very criminal he’s searching for.
