Six months after their last mission, three members of the British special-ops team Section 20 - Gracie Novin, Samuel Wyatt and Thomas "Mac" McAllister - reunite for what they think is a routine "cleanup" exercise in Malaysia. Things get complicated when their new commanding officer, borderline burn-out Alexander Coltrane, learns that a British operative, in possession of intel about a downed Russian plane, has been killed in Kuala Lumpur after meeting with Katrina Zarkova, a covert Russian operative.
The trail leads Wyatt, Mac and Novin to a Russian safehouse, where Katrina and her team of Russian soldiers are attempting to track a mysterious "package" stolen from the plane, which crashed into the ocean under suspicious circumstances. The confrontation turns bloody when members of a brutal Malaysian triad arrive, setting off a chain of dangerous encounters in the skies and skyscrapers of Kuala Lumpur.
