A military-led government sends out a Special Forces team to track down an unknown creature in an abandoned warehouse.

Sector 13 is a Special Forces team with a mission to track and eliminate vigilante alien terrorist cells. For the past 50 years, they have patrolled the earth, clearing the planet of any rogue beings who pose a threat to the military-led government. For months they have pursued one of the high ranking members of a renowned terrorist group known as 'EVO'. Having tracked down its whereabouts to an abandoned warehouse, Sector 13's RED and BLUE teams move in for the execution. However, once inside, they soon learn that the creature they set out to hunt is now hunting them. One by one, team members are picked off until only the RED leader remains - climaxing in a gravity-defying duel to the death.
