and Satish Shah
Plot
In 2010, London, Jenny Nair, an employee of UK-based company Barron Industries, introduces a new technology that allows objects from the digital world to enter the real world using the wireless transmissions from multiple devices. Shekhar Subramanium, who also works for the company, is given a final chance to devise with a video game with a difference. To impress his sceptical son Prateek (Armaan Verma), and upon the request of his wife Sonia, Subramanium uses his son's idea that the antagonist be more powerful than the protagonist.
Shekhar's colleague Akashi provides the moves of the game's characters, Jenny does the programming and Shekhar gives his face to the game's protagonist G.One, whilst the antagonist Ra.One is faceless and has substantially greater powers than those granted to G.One, including shapeshifting. Ra.One is imbibed with a self-learning artificial intelligence. The game has three levels, and either of the players can only be killed in the third level using a special gun that holds a single bullet. While designing the game, Akashi notices some malfunctions but ignores them. When the game is finally launched, it receives a standing ovation and Prateek loves it so much that he insists on playing it instantly. He logs in under the alias 'Lucifer' and proceeds to the second level, but is interrupted by Akashi. The self-aware Ra.One, being unable to end his turn with Lucifer, becomes determined that Lucifer shall die.
When the mainframe fails to shut down, Akashi calls Shekhar, who notices a problem with the game. Ra.One uses the new technology to enter the real world and breaks free and goes to find Lucifer.
Ra One first threatens Akashi and asks him where Lucifer is. When Akashi fails to reply, Ra One thinks that he is useless and abruptly abducts and wastes Akashi by knocking him off a large glass window that frightens Shekhar and mercilessly plummets and murders an innocent Akashi.
