Plot
5 men wake up inside of a factory to find themselves locked. It is revealed that 2 of the men trapped have been kidnapped and held hostage by the other three for a planned heist. However, they themselves do not know who the hostages and kidnappers are. They receive a phone call from Kaiser, the leader of the gang, who informs them that he is on the way with ransom money and plans to tip off the hostages once he arrives. They try to escape but fail, causing them to lunge at one another in despair.

Sarthak regains his memory and realizes that he is one of the hostages and that JD is the other hostage as they were both kidnapped. He informs JD that both of them are going to be killed. JD, however, is unaware as he has no memory of the incident.

Max regains her memory and is revealed to be Kaiser's girlfriend. In addition, the gang members are revealed to be Om, Sultan and Romeo. Once Kaiser arrives at the factory, Sultan regains his memories and discovers that JD and Sarthak were once business partners. Sarthak planned on selling the company, which was the reason for his kidnapping.

Kaiser gives Sarthak an opportunity to free himself by killing JD. Sarthak is tasked to kill Sultan by JD, however he tries to get Romeo to kill him instead. Romeo escorts Sarthak to the balcony of the factory and fires his gun, making the gang believe that Sarthak is dead. However, they realize that Romeo is an undercover police officer assigned to capture the gang. A shootout occurs in the factory where Sarthak finds 2 gas masks and hands one to Romeo. They fire at the tank, causing an explosion. Romeo and Sarthak escape the factory and find the police waiting outside to arrest the gang.

Plagiarism accusations
When questioned similarities with the 2006 American film Unknown, Verma claimed he did not know whether it was a rip off or not. According to him, the writer came up with the story three years before it appealed to him and he decided to direct it. He remained unfazed by its being a remake or not.

Simon Brand, who directed the original film, was shocked when he learned about Acid Factory through an Indian journalist in Los Angeles. Brand spoke to members of the industry who knew the subject and they told him it was difficult to sue the makers for plagiarism since the film had already been released in the United States, which was a common practice in India. Brand claimed to feeling enormous helplessness and frustration at not being credited for an unauthorized remake shot with four or five times more budget than his film.

Critical reception
The film received mixed reviews and failed at the box office. Deepu Lalwani of Bollywood Hungama gave the film 3.5 out of 5 stars and called it a well crafted, well-executed film with an ensemble cast pitching in competent performances. The Times of India gave the film 3 out of 5 stars and called it a sufficiently engaging film that could have broke new ground.
