A hit man killed two men in a bar, the bartender, and kidnapped a female patron. The CSIs had a hard time trying to connect the victims since the men killed seemed to have nothing in common. It was discovered that two of men, who were the likely targets of the hit, were suffering from serious medical conditions. 

Eventually the CSI were able to indentify the kidnapped woman as Camille Jordanson. Camille and Dr. Hawkes had known each other growing up. The police found a hidden case filled with fake medication in Camille's apartment, and discovered that she had been fired from her job as a nurse for stealing.  

The hit man kept Camille alive because he needed information she had regarding one of his other targets. At first Camille did not cooperate, but eventually gave the hit man the information he was after.

Analysis of the shooting victims revealed that their blood was radioactive due to the fake medication they had been taking. The fake medication was tied back to the clinic Camille had been working at. She hadn't been stealing medication but gathering evidence on the doctor running the clinic, Dr. Kumi.

Dr. Kumi and her associates were arrested after a shoot out with the police. The police tracked the hit man's location via his cell phone. Camille was rescued and the hitman was apprehended.
