Eddie Morra (Bradley Cooper), a struggling author suffering from writer's block, living in New York, is stressed by an approaching deadline. His girlfriend Lindy (Abbie Cornish), frustrated with his lack of progress and financial dependence, breaks up with him. Later, Eddie happens to run into Vernon (Johnny Whitworth), the estranged brother of Eddie's ex-wife, Melissa (Anna Friel). Vernon, involved with a pharmaceutical company, gives Eddie a sample of a new "smart drug", NZT-48. After taking the pill, Eddie finds himself able to learn and analyze information at a superhuman rate and recall memories from his distant past, with the only apparent side effect being a change in the color of Eddie's irises while on the drug—his eyes becoming an intense shade of electric blue. Under the influence, he cleans his messy apartment and writes ninety pages of his book.
