Season 1 of "The Undeclared War" left us on a superb cliffhanger, with Vadim's line going dead and us all assuming he has sacrificed himself for the cause, which means when we dive into season 2 we will be picking up the pieces from that potentially huge moment.
The latest episodes will see Danny Patrick (Simon Pegg) and his team discovering that it's not Russia behind the cyber attack they've been dealing with all along, with a new, unknown threat lurking in the shadows. There's six episodes to come, and lots more plot twists, we're sure.
If you're ready to be on the edge of your seat and dive into the latest episodes, we'll show you how to watch "The Undeclared War" season 2 online from anywhere.
