Cobb and Arthur are "extractors"; they perform corporate espionage using experimental dream-sharing technology to infiltrate their targets' subconscious and extract information. Their latest target, Saito, is impressed with Cobb's ability to layer multiple dreams within each other and offers to hire Cobb for the supposedly impossible job of implanting an idea into a person's subconscious; performing "inception" on Robert, the son of Saito's competitor Maurice Fischer, with the idea to dissolve his father's company. Saito promises to clear Cobb's criminal status, allowing him to return home to his children.
