A fighter pilot is shot down. An RAF fighter (setting the style: this is a British film). She takes refuge in a bunker. We are in Afghanistan. Where nothing is what it seems, but always worse. The bunker is (was?) a laboratory. Secret, naturally. Russian (once again the baddies that the film world needed). A biological weapons laboratory. Agent Orange, mustard gas, napalm? Far from it: they had set about playing with the nucleic acid that contains the genetic instructions used in the development and functioning of all living organisms… including aliens! Directed by our old friend from Dog Soldiers (2002), The Descent (2005) and a handful of chapters of “Game of Thrones” (2011-2019). Extreme action. Endless gore.
