With Max now determined to turn the tables on White and pro-actively lead a transgenic resistance against the fast growing and dangerous xenophobia that is sweeping the country, events unfold that place our heroine in a potentially more vulnerable position than ever before. Attempting a rescue of three of her "brothers" imprisoned and on the verge of execution, Max's misguided trust in a seemingly helpful, but odd individual places her directly in the line of fire when the man's close familial connection to White is revealed. Double-crossed and potentially on her own due to a recent estrangement from Logan, Max must not only figure out a way out of her seemingly deadly predicament but also turn the tide on White's plans to expose the transgenics to a less than accepting populace. With time running out and Max, Alec and the rest of their kind backed into a corner from which there may be no escape, we head toward the final showdown of humans vs. transgenics.
