When two members of the Pakistan Regional Fund (PRF) are abducted and killed, the FBI suspects a terrorist attack may be imminent. The PRF is suspected to have ties to jihadist groups and was on the FBI's terrorist watch. The assassination of two of its members raised a red flag. Caught in the crossfire is Charlie's friend and colleague, PRF member Phil Sanjrani, who sent sensitive but harmless biological farming research he developed to colleagues in Pakistan. Disgusted that his friend was being prosecuted, Charlie works under the assumption that the PRF is a legitimate charity, but Don isn't sure, and along with special agent Sam Fraley, he investigates the PRF's past.
They discover that Charlie is correct, and that a rogue arms dealer had infiltrated the PRF to use its funds to further his gun smuggling business and who had killed the two members after they had discovered his secret. However, in order to save his friend, Charlie takes on the FBI and proves that Phil's research was only sent to help, and loses his security clearance in the process.
