Kristen Black, PI, is forced by an agent of the dreaded intelligence service, Military Security, to find a small metal case that's missing. About the size of a paperback book, the case is very cold to the touch, and it has a keypad that responds to body heat. The agent won't tell Kristen what the mysterious item is or why he's so frantic to retrieve it. Right from the beginning, Kristen is under constant threat by other parties who are also looking for the case and are willing to kill to get it. As the search continues and the body count increases, Kristen begins to suspect that the metal case is not just a threat to the agent but it's also a threat to everyone else in the world, including her.
