Baby is a getaway driver in Atlanta. As a child he survived a car crash, which killed his parents and left him with tinnitus. He finds catharsis in music, typically using iPods to soothe his tinnitus. Baby ferries crews of robbers assembled by criminal mastermind Doc as recompense for the theft of a car containing Doc's stolen goods. Between jobs, he remixes snippets of conversations he records and cares for his deaf foster father, Joseph. He meets a waitress named Debora, and they start dating. Baby's next robbery goes awry after an armed bystander chases them down, but Baby evades him and the police. Having paid his debt, Baby quits his life of crime and starts delivering pizzas. Doc interrupts Baby's date with Debora and insists he join a post office heist, threatening to hurt Debora and Joseph should he refuse.

The crew consists of easygoing Buddy, his sharpshooter wife Darling, and trigger-happy Bats, who takes an immediate dislike to Baby. When the crew attempts to purchase illegal firearms, Bats recognizes one of the dealers as a covert operative and opens fire. They kill most of the dealers. Afterward, Bats makes Baby stop at Debora's diner, unaware of their romance. Baby, aware of Bats's homicidal habit, stops him from killing her to avoid paying. Doc is furious, revealing that the dealers were corrupt cops on his payroll. He decides to cancel the heist, but the crew overrule him. Baby attempts to slip away late that night, hoping to take Debora and leave Atlanta, but he is stopped by Buddy and Bats, who have discovered his recordings and believe he is an informant. Baby convinces them and Doc of his innocence by playing them a tape of one of his remixes.
