Season 6, episode 5

Debut date: FRIDAY, FEB. 22 (10:00-11:00 p.m.)

Following a high-speed jungle ambush in Myanmar, the suitcase nukes end up in the hands of Jean-Baptiste Zaza (Chris Obi), 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 (Victoria Smurfit), a DEA agent with inside intel on Zaza and Dagon (Fish Chaar), his second in command. With the suitcase on the verge of being sold to a jihadist, Coltrane (Jamie Bamber) tasks Novin (Alin Sumarwata) with impersonating the buyer in order to ascertain the WMD's location. Meanwhile, Colonel Beshnov (Marek Vasut), the Russian Alpha Group leader, surprises Pavel (Alec Newman) with a revelation about Zarkova (Yasemin Allen).

Written by Jack Lothian; directed by Steve Shill.
