History
Following the tests by Dr. Henry Hallson discovering one member of the group possessed an incalculably and superhumanly powerful mind. Adam killed Henry with telekinesis; however Henry had time to scrawl on the wall his name as a clue before he died.

The next day Professor Jim Tanner (the protagonist) was called by the police on suspicion of being the murder, as Adam has wiped the mind of his degree granting colleges, meaning he appears to have suffered academic fraud.

Adam then directly assaults Tanner, first teasing him by making simple alterations (causing a stop sign to change don't walk to don't run) before forcing him through a series of mind breaking illusions and peaks of human endurances bringing him to the point of death, however Tanner survives. Now well aware of the danger of Adam, Tanner leaves and tries to track down Adam before he tries again.

Upon learning more on Adam's origin Tanner returns and tries to find out more from Hallson's window, but Hart got there first, and had already wiped her memory of her husband, and removed all evidence of his existence. Hart then turns on another scientist Melniker, but first teases Tanner, by publishing headlines of his "Don't run" in the papers. He then kills Melniker.

Hart then again tries to kill Tanner, by pretending to be under attack from him, himself tricking him into entering an elevator shaft, where he tries to crush him with the elevator, but once again Tanner escapes. He then pretends to join them and urges Tanner to kill the remaining two suspects, but Tanner refuses, knowing one of them is innocent.

While trying to talk to Dr. Van Zandt, but after talking to his wife, Adam tries to run him down, Tanner escapes, but Adam manipulates his car so that it’s out of control and Tanner once again barely escapes with his life. Adam meanwhile sets Van Zandt's house alight and traps the two inside.

After confronting Scott, Tanner realizes the Truth and decides to confront Hart himself, in laboratory, Hart lets the full power of his mind loose on Tanner, making him experience incredible extremes, freezing cold, burning heat, before finally the darkness of space. However in Tanners mind everything snaps, and he realizes that Adam wasn't the genius found by Henry, for why would someone who had been so careful all there life expose themselves. The Genius was him.

Realizing this Tanner begins to fight back, Adam unable to take the strain is killed by Tanner telekinetically squeezing his heart, ending his murder spree.
