In a dystopian 2021, Johnny (Keanu Reeves) is a data trafficker who has an implant that allows him to securely store data too sensitive for regular computer networks. On one delivery run, he accepts a package that not only exceeds the implant's safety limits - and will kill him if the data is not removed in time - but also contains information far more important and valuable than he had ever imagined. On a race against time, he must avoid the assassins sent to kill him and remove the data before it, too, ends his life.
