Jonathan Ecks, an FBI agent, realizes that he must join with his lifelong enemy, Agent Sever, a rogue DIA agent with whom he is in mortal combat, in order to defeat a common enemy. That enemy has developed a "micro-device" that can be injected into victims in order to kill them at will.
Callum Crane, a lawyer and would-be federal judge, jeopardizes his chances at a judgeship by forcing himself on his secretary. He then worsens the situation by trying to have the woman murdered. Further complicating matters, he assigns the task to a young man who, unbeknownst to Crane, is actually his son, Nathan. Nathan refuses to do the deed, but not before informing several people, one of whom tries to take on the job.
