Acid Factory 2009

Cape Town Police's Assistant Commissioner Ranbir Singh travels to Durban to meet with undercover Agent Romeo and assigns him a special task. Shortly thereafter Romeo is attacked, loses his consciousness and when he regains it, finds himself trapped in an acid factory along with four other males. One of the males is tied to a chair, while another is handcuffed. All of them soon realize that due to the presence of Pentane - a gas that induces memory loss - they are not even able to remember their names. They do manage to gain each other trusts' and even release their two comrades. While they discuss their situation, they are confronted by an unknown gun-toting female, also suffering from memory loss, and soon realize that two of them are actually abducted and are being held for ransom by the other three.
