Olivia Wagner is one of the top CSI's in the state. She's worked many tough cases before. But this one is different. It's taking the lives of those who deserve to live, and ruining the lives of others. And on top of it all, FBI Detective Jack Murray is stuck like glue on her side for the entirety of the case. And she's not sure if that's a good or bad thing. Jack Murray hates this case with all of his being. It's personal. Very personal. He wants to stop it with every part of him. And when Olivia Wagner works the case with him, he can barely stop his heart from exploding. And explosions are dangerous. Very dangerous.
