Output: In 2021, Johnny is a mnemonic courier with a data storage device implanted in his brain, allowing him to discreetly carry information too sensitive to transfer across the Net, the virtualreality equivalent of the Internet. While lucrative, the implant has cost Johnny his childhood memories, and he seeks to have the implant removed to regain his memories back; his handler, Ralfi assigns him one more job that would cover the costs of the operation which are extremely expensive, sending Johnny to Beijing to collect the latest information. Johnny is told that the information exceeds his current memory capacity of 80 gigabytes, but he acquires a compression unit that effectively doubles the amount he can hold. He meets with the client, a group of frantic scientists who tell him that they want him to carry 320 gigabytes of memory; Johnny accepts this, knowing that the overflow data will by uploaded directly into his brain which can cause psychological damage and death if not removed within a few days. Johnny uploads the data to his storage, with the scientists selecting three random images from a television screen to use as an encryption key. Just as the scientists are about to send the key to the datas receiver in Newark, New Jersey, they are massacred by Yakuza. Johnny manages to escape with a portion of the encryption key. While returning to Newark, Johnny is pursued by Pharmakom, a global pharmacological company; its executive Takahashi hired the Yakuza to recover it. However, the Yakuza, led by Shinji, want to take the data and claim it for themselves. Takahashi discovered this, and instead hired Karl, the Street Preacher, to recover Johnnys head. Johnny finds Ralfi is in the Yakuzas employ, and prepares to kill Johnny to recover the storage unit, but Johnny is rescued by Jane, a cyberneticallyenhanced bodyguard, along with help from the antiestablishment LoTeks and their leader JBone. Jane takes Johnny to meet Spider, a doctor who installed Janes implants. Spider reveals he and his allies were the intended recipient of the data Johnny has, which they believe is the cure for nerve attenuation syndrome NAS, a plague ravaging mankind due to overdependence on technology. Spider claims Pharmakon discovered the cure but refused to publish it, profiting on the costs of mitigating the effects of NAS. Without the full encryption key, Spider cannot recover the data, nor safely remove the implant without killing Johnny or destroying the data, and suggest he see Jones at the LoTek base, Heaven. Karl follows Johnny to the clinic and kills Spider, but Johnny and Jane escape. At Heaven, they find Jones is a dolphin once used by the Navy for his decryption capabilities. Jones attempts to discover the remainder of the encryption key to the data, but Heaven is soon attacked by the Yakuza, Takahashis forces, and the Street Preacher. Johnny, Jane, and the LoTeks fight off all three groups and emerge victorious, killing Shinji, the Street Preacher, and their agents. Takahashi, who was shot in the crossfire, provides Johnny, in a dying gesture, with a portion of the remaining key. While this helps, Johnny is told by JBone that he must hack his own brain to find the final portion, unlocking the data so that the LoTeks can download it and transmit it across the globe. Johnny and Jones again start the procedure but find themselves helped by a mysterious artificial intelligence that operates from Pharmakoms mainframe, providing the last portion of the password to unlock the data. The data for the NAS cure is safely recovered and Johnny discovers he can now recall his memories of his youth, including his mother and family. As Johnny recovers from the process, he, Jane, and the LoTeks observe the Pharmakom building on fire, a sign that the cures transmission was successful.
