Recent US citizen Amir Alhabi, an immigrant from Syria, is found dead in a building next to where his stripped cab is found. He and his cousin Jamal were the owners of the cab. Investigation of the cab's GPS shows that Amir picked up a fare earlier in the day, drove in a circle and then let him out at the same spot. The fare is identified as Fariq Yusef, a 'security attache' for the Syrian Embassy. When Castle and Beckett go to investigate a storage locker, identified from a note on Amir's phone, they find a weapons cache and are exposed to radioactive Cobalt 60. Homeland Security Agent Mark Fallon takes charge as Amir used to work in the Syrian weapons program and it is feared he created a nuclear weapon. Suspecting something didn't feel right, Castle, with Beckett's help, contacts Fariq Yusef to get more information. When Agent Fallon finds out, they are both removed from the precinct. Unofficially, they keep looking into tracing a payment to Amir and why he had a camera installed ... Written by KGF Vissers

A major plot point of this episode has to do with a so-called cobalt-60 "dirty bomb." Castle and Beckett are supposedly exposed to high levels of cobalt-60 radiation. Aside from the fact that no cobalt bombs have ever been built, the cobalt "tamper," as the shell of material surrounding the nuclear core of the weapon is called, is not radioactive before the explosion. The explosion transmutes the ordinary, inert cobalt-59 into its highly radioactive isotope, cobalt-60. Thus, no one could possibly be exposed to cobalt-60 radiation before the bomb goes off, unless the cobalt had been bombarded beforehand by a particle accelerator, a pointless exercise, as cobalt-60 rapidly loses radioactive effectiveness after transmutation, with a half-life of less than 5-and-a-half years.
