Smart, tough Los Angeles FBI agents Jack Harper and Oscar Hidalgo meet their match in a diamond smuggler, Steinbach, who seems to have almost superhuman powers. Arrested during a clever sting operation, Steinbach tells the team of agents he will kill them, and sure enough, one by one, they start to die. Worse, Jack can’t begin to pin it on Steinbach, who is, after all, in prison. Soon, however, Steinbach makes a deal with Homeland Security and is freed with total immunity.
Jack is pretty sure that he and Oscar could be next. But, as it turns out, Steinbach is not the only menace. Two of the agents who were killed turn out to be dirty. Jack and Oscar tour the seamy side of L.A. in hopes of finding clues, but they get way more than they bargained for.
