What Is “Radio Active” About?
A terrorist cell is preparing a chemical bombing somewhere in the city, but the team does not know where the attack will happen. To find answers, the agents work with an old-school code breaker who has agoraphobia. Together, they tackle a cipher that initially appears impossible to solve.
The mission brings a specialist’s expertise into the investigation while Colin and Bill face separate personal concerns. Colin wrestles with Toni’s return to fieldwork, and Bill prepares for Katie’s response to his recent admission.
Those developments give “Radio Active” two continuing character threads alongside its immediate case. The preview does not disclose Katie’s response or how Colin handles Toni’s return, leaving those questions for the episode.
“Radio Active” was written by Alex Berger and directed by Milena Govich.
Tom Ellis and Nick Gehlfuss Lead the CIA Cast
