Lullaby is a strong-willed, 2nd-generation covert assassin, viewing the world through a black and white lens. Typically, she adopts a new look and identity for each mission before moving-in next door to a potential target, and presenting herself as a friendly (or troubled or sexy or mysterious) neighbor. But, upon receiving orders to “terminate,” Lullaby does so with clever — and sadistic — precision. Now, Lullaby is mired in a “gray area”; she must choose whether to remain a government-sanctioned killer or walk away for love. That is, of course, assuming the choice will be hers to make.
