He starts using MDT-48, an experimental drug granting heightened intellectual, creative, and learning powers, and enabling its user to see meaningful patterns in large amounts of disparate data.
His trading escapades don't go unnoticed, and he is offered a job by billionaire tycoon Carl Van Loon, mediating the merger between entertainment giant MCL Parnasis and Abraxis, the country's second largest Internet service provider – a deal he sees to completion.
He further learns the full scope of the side-effects from his ex-wife Melissa, who had dabbled in the substance and suffered permanent neurocognitive damage, prompting him to gradually discontinue use of the drug.
Eddie initially reduces his intake to half a pill a day, but this quickly proves insufficient to maintain the level of mental acuity required to work out the details of the merger, and he is forced to increase the dosage.
His stash running out, Eddie makes a desperate attempt to blackmail the pharmaceutical conglomerate responsible for developing MDT into providing him with continued access to the drug.
Facing imminent death from withdrawal, Eddie comes to terms with his own actions and travels to Mahopac, New York, where he seeks redemption by leaving a bag full of cash at his ex-wife's doorstep.
He then continues driving aimlessly up north, and eventually checks into a remote motel along the Vermont highway, where he pens his account of the last few months of his life and the events leading to his ultimate downfall.
As he drifts into a semi-conscious state, Eddie watches as the President – visibly under the influence of MDT – announces the deployment of US troops into Mexico in a televised address to the nation.
