Born in Russia but brought up in New York by wealthy adoptive parents, before rejecting them to live on the streets with her friends, Wallis Stoneman has never known too much about her past. This lack of knowledge might turn out to be deadly, though, when a chance encounter leads to her being given a letter from her birth mother. As Wally tries to track her down, she and her friends enter a murky world where the stakes are high, the truth is hidden, and every move they make could be their last.
