Reyna Royal, an assassin who's part of the top in her league, gets a very strange request from a client. To become a nanny. With demons buried deep with the aid of medication, she gives it a two-week trial, but it's more than she can handle. As demons are unleashed, medications become weak and she's stuck in the middle of war for power, land and money, she must make a choice; trust to handle her problems with ease, or continue to shut everyone out around her and burden her problems herself.
