Cinemax's Strike Back: Origins comes to a thrilling conclusion on Friday, but you can get a sneak peek at it now with our exclusive video from the final episode.

While John Porter (Richard Armitage) tries to escape from Pakistan, Collinson (Andrew Lincoln) raises the suspicions of their colleagues, and ultimately decides to take the mounting situation into his own hands.

The major guest stars from last week - Toby Stephens (Black Sails) and Alexander Siddig (Star Trek: Deep Space Nine) - continue their arcs in this last installment.

Here's exclusive video previewing what happens to Porter this week.

And as if that's not enough drama, Porter and Collinson will find themselves under attack. Here's a preview of that unhealthy situation.

It all adds up to one thrilling last stand. The Strike Back: Origins finale airs Friday, November 29 at 10 PM ET/PT on Cinemax.
