The Lair plot
"Unlocked. Unleashed."
Lieutenant Kate Sinclair, a pilot in the Royal Air Force, is shot down over Afghanistan. There, she finds refuge in an abandoned underground bunker after being chased by insurgents. In the bunker, she unwittingly releases deadly, artificial, biological weapons made by man. Sergeant Tom Hook is tasked with leading a unit to find Sinclair and is assisted by a handful of British SAS troops. They will have to face the insurgents and the deadly creatures that are half human, half alien during the rescue mission.
