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.

As Wyatt convalesces, Coltrane, Mac and Novin embark on a covert, 24-hour mission inside Russia to extract an FSB analyst with potentially vital information. Katrina questions Pavel's true identity, but chooses to stand by her commanding officer. Tracking Hassan to an outpost in the Indonesian jungle, Section 20 ends up facing off with Pavel and Katrina, as Chetri zeros in on the nuclear suitcase in a Jakarta mall.
