In the end

It's been three months since Amy escaped New Hope. Three months since she's seen Baby, or Kay, or Rice. And she's been surviving on her own, like she did before she was "rescued" and taken to what she thought was a safe haven. Then, in the midst of foraging for supplies, her former fellow Guardian's voice rings out in her earpiece. And in a desperate tone, Kay utters the four words Any had hoped she would never hear: Dr. Reynolds has Baby. Now it's a race against time, for Baby is in imminent danger, her life threatened by the malevolent doctor who had helped start the end of the world. In order to save Baby, Amy will have to make her way to Fort Black, a former prison-turned-survivor colony. There she will need to find Ken -- Kay's brother -- for he holds the key to Baby's survival. (Series conclusion)
