AKIRA (Movie) Wiki

Following the disaster wrought upon the world by a mysterious being called ‘Akira’, Neo Tokyo is now in social and economic turmoil. In such a decaying city, feisty Kaneda and his shy friend Tetsuo survive by running around in a biker gang, chasing local rivals, and generally evading the police. Everything changes, however, when Tetsuo crashes into a strange-looking boy during a bike chase and the military ends up taking him away.

When he eventually returns to his friends, he’s no longer the same weak little boy they always knew – in fact, a military experiment has turned him into something beyond human imagination. While the military is intent on reclaiming its specimen at any cost, Tetsuo is sick of being bullied around and is about to show everyone, including his friend Kaneda, exactly who is boss.
