Only minor changes to the original film’s storyline . . .
“Kaneda is a bar owner in Neo-Manhattan who is stunned when his brother, Tetsuo, is abducted by government agents led by The Colonel.
Desperate to get his brother back, Kaneda agrees to join with Ky Reed and her underground movement who are intent on revealing to the world what truly happened to New York City thirty years ago when it was destroyed. Kaneda believes their theories to be ludicrous but after finding his brother again, is shocked when he displays telekinetic powers.
Ky believes Tetsuo is headed to release a young boy, Akira, who has taken control of Tetsuo’s mind. Kaneda clashes with The Colonel’s troops on his way to stop Tetsuo from releasing Akira but arrives too late. Akira soon emerges from his prison courtesy of Tetsuo as Kaneda races in to save his brother before Akira once again destroys Manhattan Island, as he did thirty years ago.”
Except for the action moving to Neo-Manhattan instead of Neo-Tokyo in the original and Kaneda being a bar-owner instead of a bike gang leader not much has been changed really.
