(INTO PHONE) Letter opened in Special Agent Gibbs's office dispersed a fine white powder. (TONY/ KATE AND PITT WALK TO THE ISOLATION CUBE)
DOCTOR PITT: Well, it's not The Four Seasons, but let's hope you're not here long. A gene-altering bio-attack. ABBY: However, there is an antidote. ABBY: They found a Navy suspect? And it gives him...
KATE: Hope. And the scent. Cassie, I already downloaded the NCIS report from the rape investigation. GIBBS: Academy seniors. GIBBS: To find out who sent the letter. He has the same chance of survival as those infected in plagues of the past, probably better since he will be healthy and young. I can rub my tummy and...
GIBBS: DNA testing cleared them, closed our investigation. ISOLATION ROOM
TONY: ... Great old time actor. Is that Sarah? It's a rape case. It's dead. Look at the plasma. MCGEE: I get colds all the time. May I? SARAH: I... heard they were all cleared. TONY: Are you kidding? There's another one inside. They're not going to be able to hear me. This is barely one. When his sputum becomes bloody, he'll only have a few hours to live. Who the hell are you? You cannot leave autopsy.

Summary: All hell breaks loose at the NCIS office when Tony opens a mysterious letter containing a small puff of white powder which may be a deadly bacteria. The whole office is put into lockdown and quarantined, leaving only the lab and autopsy operational. Kate and Tony are isolated into a bio-hazard isolation room while McGee and Gibbs are forced to seal themselves in hazmat suits to be able to help. The letter inside tells them that there is a cure, but in order get the cure before a 32-hour time window expires, NCIS must re-investigate an unsolved rape case from four years earlier where all the prime suspects (navy academy seniors) were cleared by DNA. As the time window ticks away, and it becomes clear that one person is infected, Gibbs must find those responsible before he loses one of his agents.
