Limitless Description:

Aspiring writer Eddie Morra is a loser at work and romance. Recently dumped by girlfriend Lindy, he heads back home when he meets his former brother-in-law Vernon, who gives him an experimental drug called NZT to increase his creativity. Eddie finds the results more than impressive and decides to seek out Vernon to ask for more pills, but a visit to Vernon’s house leads to a dead body. Eddie dutifully calls the police but pockets the NZT he finds hidden in a stove with a large amount of money.
