Memory restoration neural stimulation is becoming real

In 1985 Mexico City, Heinrich Treadway tries to escape the authorities and a man named Bathurst. Treadway and his associates, Abel and Leona, speak about "the Egg", which Treadway stole from Bathurst. Treadway tells Abel that if he does not survive, the latter must remember to "look inside". He drives off a bridge, jumping from his car in mid-air and onto a crane 150 feet away. However, Treadway watches helplessly as Bathurst arrives and kills Abel and Leona. In 2020 New York City, Evan McCauley has schizophrenia. Because of past institutionalization and violent behavior, he cannot get a job. He forges a katana for a local gangster, even though he was never trained as a bladesmith. After the deal goes south, Evan makes his escape but is later arrested. A man at the police station introduces himself as Bathurst, claiming they have known each other for centuries and that Evan is Treadway. Nora Brightman, Leona's reincarnation, helps Evan escape and explains that a group of 500 individuals, known as the Infinites, can remember all their past lives, divided between two groups: the Believers, including Nora, who want to make the world better, and the Nihilists, including Bathurst, who want to end the world. The Nihilists developed a weapon known as the Egg capable of destroying all life on Earth, although Treadway had stolen and hidden the Egg shortly before dying. Most Infinites remember their past lives around puberty, which is why Evan was diagnosed schizophrenic. Bathurst has trapped 200 Believers in computer chips with his Dethroner weapon, including Abel. Nora takes Evan to the Hub where he undergoes training and treatment to regain his memories with limited success due to electroshock therapy and a car accident. As the Nihilists raid the Hub, Evan, Nora, Kovic and Trace seek the help of another Infinite, Artisan, who uses a machine to restore Evan's memories with a near-death experience. Evan learns that Treadway had hidden the Egg inside of his own body before committing suicide to protect it. Overhearing this, the Nihilists kill Kovic and Trace and recover Treadway's body with the Egg. Evan, Nora and Artisan attack Bathurst's Scotland estate, killing his forces, including Bathurst's assassin Shin. As Evan chases Bathurst's plane, a mortally wounded Nora sacrifices herself to destroy the repository of contained Believer souls, including Abel, releasing them to reincarnate. Tapping into Treadway's superhuman abilities, Evan fights Bathurst, surviving the Dethroner thanks to a steel plate in his head. Evan contains Bathurst with the Dethroner and disarms the Egg, sinking into the depths of the ocean with it. Nora and Abel are reborn and they reunite at the Beginning around fourteen years later. An older Artisan visits a reborn Evan in Jakarta, Indonesia and offers him Treadway's katana. Evan regains his memories upon recognizing Artisan.
