In a world where werewolves secretly live alongside humans, Ji-u Han runs a detective agency and happens to be a powerful werewolf herself. Her life changes when famous actor Yuseung Cheon "accidentally" hits her with his car. After several suspiciously convenient encounters, Ji-u becomes determined to keep him close.
Yuseung possesses a rare power that can make werewolves stronger through touch, something Ji-u desperately wants. But Yuseung has his own agenda—he's searching for information on important figures in the werewolf world so he can destroy them. As their goals clash, will they get what they want... or end up falling for each other instead?
