Edward "Eddie" Morra (Bradley Cooper) is a writer who lives in New York City. He has recently been dumped by his girlfriend Lindy (Abbie Cornish) in addition to failing to meet the deadline to turn in his new book, which he hasn't started yet. One day, Eddie comes across Vernon Gant (Johnny Whitworth), the brother of his ex-wife, Melissa Gant (Anna Friel). Vernon is a drug dealer, and he offers Eddie a sample of a new (fictional) nootropic drug, NZT-48, claiming it allows humans to access 100% of the brain's power, as opposed to the "normal" 20%.
