Finally free of her mother’s controlling ways, Natalia, a quirky misfit, heads to New York City after learning her family’s darkest secret—Daniel, a stepbrother previously unknown to her. With her desire to be loved and accepted by someone for the first time, Natalia pretends to be the person her half-brother expects. However, behind his back, Natalia is someone completely different.

Natalia works for Stuart, a powerful and eccentric corporate executive, eliminating costly retired pension recipients one by one. Not completely without emotion or a moral compass, Natalia tries to find annoying habits or irritating personality traits to justify her doings. Getting better at what she does, with good reason and even better pay in hand, she makes each hit look like natural causes.

But after spending more time with Stuart, his wife, and a new love interest, the innocent facade she presents to Daniel begins to crack and her true colors start to slip through. With Daniel’s suspicion growing, Natalia finds herself at a crossroads: either conform to Daniel's expectations or embrace her true identity.
