Amanda finds Nick, still crestfallen over the death of his partner, drunk in a bar. She attempts to apologize for what happened, but Nick tells her to leave. Outside the bar, they witness a shooting, but they are too late to save the victim. After fighting off the killers, Amanda sees them enter a car that also contains Mario Cardoza, an immortal hit man. Realizing that it was not a simple mugging, she and Nick try to uncover the truth and stop Cardoza before he can reach his next target.

Nick accepts an undercover assignment in which he has to infiltrate the Romanian embassy and recover a set of secret plans that had been stolen by one of its employees, and he asks for Amanda's help. Also, Amanda is being hunted by Stefan Collier, an immortal who insists that, despite not knowing her personally, she is next on his list.
