Strike Back

Section 20 are reunited to rescue a biochemist who's been taken as a hostage in Kosovo by the Albanian mafia. But as the situation escalates, a sinister conspiracy to cover up the development of the weaponized virus unfolds.

After catching wind of a feud brewing between Edon and his son Loric, Section 20 launches a raid on their family business; wedding arrangements between the Demachi and Vironi families sour; Mac considers a career-changing offer from Coltrane.

S20 is in Tel Aviv, tracing a man with stolen Russian military tech that he plans to sell to Zayef and Mahir. A notorious Israeli gangster makes matters even more complicated. Luckily, S20 picks up a highly-trained friend along the way.

Novin is forced to cooperate with Topal and Danny, as Spencer gives the squad an ultimatum. After an explosive stand-off with Zayef and Mahir, Spiegel threatens to blow the lid off S20's operations in Tel Aviv, and later, the squad's arrangement with the local police reaches its tipping point. Meanwhile, a serious threat is posed to S20's alliance with Zarkova.

When Zayef's location is compromised, S20 raids the premises, leading to Mac defying orders to keep his team safe. Suspecting that Zayef plans to deploy the stolen military tech during a U.N. conference in Munich, S20 sets out to stop him.

Long after the incident in Munich, Wyatt and Novin reunite with Mac, who has since left the military. But while he lives out a seemingly idyllic existence with his wife and daughter, his violent past haunts him.

Spencer joins S20 to take down Zayef for good. But when intel leads them back to the Demachi's, S20 finds itself embroiled in a feud that may expedite Zayef's plans and place military-grade weapons in the hands of terrorists across Europe.

S20 plans to storm a freighter carrying weapons, but when Spencer administers a kill order, Coltrane grows suspicious. As members of S20 contemplate following their conscience, Zayef divulges intel that could drastically change their fate.

With Chetri in the wind and Carolyn on their tail, Novin, Wyatt and Coltrane are blacklisted and left with scant resources. S20 seeks the help of Russian allies to combat Russian foes, and the hunt for Zayef's hard drive marches on.

After receiving shocking intel from an unlikely Russian informant, S20 decides to reunite for one final mission to track down Arianna and avenge their comrades. This time, however, they're doing things a little differently.
