Section 20's search for the missing nuclear warhead leads them to Goa, India, where three scientists have been kidnapped by Gopan, a militant under orders from a mysterious "kingfisher." When one of the scientists escapes, the team catches up to him and his daughter, gaining valuable intel on Anjali Vartak, a rich Hindu with a personal vendetta against Muslims. S20 infiltrates a suspicious fundraiser as Coltrane and new S20 computer whiz Olivia Chetri deal with a breach in security.

Following a high-speed jungle ambush in Myanmar, the suitcase nukes end up in the hands of Jean-Baptiste Zaza, a brutal Rwandan drug lord with a jealous streak. Even as they continue to suspect Zarkova's motives, Section 20 journeys to the Punchan Province and connects with Lauren Gillespie, a DEA agent with inside intel on Zaza and Dagon, his second in command. With the suitcase on the verge of being sold to a jihadist, Coltrane tasks Novin with impersonating the buyer in order to ascertain the WMD's location. Meanwhile, Colonel Beshnov, the Russian Alpha Group leader, surprises Pavel with a revelation about Zarkova.
