When the CIA tracks a radical Islamist terrorist, they call in a highly-trained special Operations Unit, including an all-female team, codenamed 'Vanquishers', to hunt him down at his covert base near the Thai border. A lethal fighting force with a license to kill, the Vanquishers infiltrate the hideout and engage in a bloody gunfight. But when the extraction helicopter leaves without them, they realise they have been double-crossed and left to perish behind enemy lines. Two years later in the midst of a terrorist onslaught in Bangkok, the CIA is deployed to flush out the perpetrators - offering the single surviving Vanquisher an opportunity for retribution. Her vengeance must be quenched, but will she again, live to tell the tale?
