Getaway

Washed up former race driver Brent Magna (Ethan Hawke) arrives home to find his house ransacked and his wife, Leanne, missing. He then receives a phone call from a mysterious man known only as The Voice (Jon Voight), who reveals himself as the kidnapper of Magna's wife. The man tells Magna that he must follow a set of instructions precisely in order to be reunited with his wife. The Voice orders Magna to steal a specially customized Shelby Mustang from a parking garage. The Voice warns Magna that if he does not follow the instructions or is caught, Leanne will die.
Magna sees two police officers chasing him and speeds off. Being a skilled driver, he is able to evade them with ease, eventually setting a trap to cause one to crash into the other. Despite more police cars joining the pursuit, Magna is able to out maneuver them. Magna is again contacted by The Voice, who directs him towards his next task. He tells Magna to speed up and take some perilous turns, eventually being forced to crash through a park, ice rink, and shopping center, nearly killing numerous civilians in the process. The Voice calls to congratulate him and tells him to keep moving. Magna is ordered to crash into a water truck and run through a red lighted intersection, causing accidents in his wake. Magna is then ordered to park in a construction zone and await further instructions. While Magna is waiting, a young woman, who is armed with a gun, known only as The Kid (Selena Gomez) attempts to steal Magna's car, but Magna overpowers her and takes her gun, and then takes her with him on The Voice's orders. The Voice then orders Magna to kill The Kid. Magna refuses, and The Voice says that keeping her alive was the right choice, as he will need her help. As Magna and The Kid drive off, with more police in pursuit, she reveals that the Mustang is, in fact, her car, and that she was told, by a police officer, it was stolen. Magna realizes that their meeting was orchestrated by The Voice.
After the Voice assigns Magna another destructive task, The Kid reveals herself as a skilled computer hacker and the daughter of the C.E.O of a large bank. The Voice contacts Magna again and orders him to upload the contents of a USB flash drive into a computer before 11:30 pm. Upon reaching the designated area, a power plant, The Kid attempts to hack the computer in order to contact the police. She appears to succeed, only for The Voice to reveal that he set up the computer as a trap for her, framing her as the person who destroyed the plant. The plant suddenly overloads and explodes, blacking out a large portion of the city.
The Voice gives Magna his final task: to rob the bank owned by The Kid's father. The Kid points out that there is no actual money at her father's bank; it is an investment firm which holds all of its assets on computers. Gradually, the duo realizes that they are not actually committing a heist, but are merely providing a distraction for the police while The Voice executes the real robbery and subsequently frames them for it.
As The Voice's men attempt to commandeer an armored car carrying sensitive hard drives, Magna surprises and overpowers them, succeeding in taking the drives. Now fleeing from the police and The Voice's men, Magna calls The Voice and offers to release the hard drives in exchange for his wife. The Voice accepts and directs him to an airplane hangar. While it appears that Leanne is about to be returned, The Kid deduces that The Voice is planning to have them all killed when the deal is done. As Magna, Leanne, and The Kid attempt to escape, the police arrive, and in the ensuing chaos, a man Magna assumes to be The Voice grabs The Kid and drives off with her. Magna leaves Leanne with the police and pursues.
Following a high speed chase, both cars are destroyed, Magna rescues The Kid, and the police arrest the mysterious man. Leanne and Magna are reunited. However, Magna receives a phone call from The Voice, revealing that the man who was busted was no more than a decoy. The Voice thanks Magna for his help and hangs up. It is revealed that The Voice was in fact controlling the entire operation from a bar in the United States. He checks his balance, revealing that almost 3 billion dollars have been transferred to his account, and walks out of the bar.
