Castle's clever idea help him and Beckett find the dirty bomb but they get locked in a refrigeration container. Luckily, Ryan and Esposito ignore orders and find them before they freeze to death.. Agent Mark Fallon lifts their official ban from the case and follows Castle's next ideas about identity, widows and an Afghan-military connection. Add Fallon's interrogation zeal and they're just in time to discover the dark motive and find the bomb but it is armed and about to explode in the middle of Manhattan.
