Jack Stanfield (Harrison Ford) is a bank's security chief who has designed a computer system & firewall to protect his employer from fraud. One day, after being introduced to a man named Bill Cox (Paul Bettany) who is interested in working with Jack on a security project, Jack finds himself ambushed and staring down a gun barrel. The man holding the gun is Cox. When Jack arrives home the motive for the meeting becomes clear: Cox & his gang of violent, psychopathic thieves want Jack to hack through his employer's computer security & transfer $100 million to Cox's bank accounts in the Caymans. Failure to comply means the murder of Jack's family. Stanfield realizes this will implicate him as an embezzler but he complies. However, even after Cox has the money, it becomes obvious that he had no intention of letting anyone live and kidnaps the family to kill them & hide their bodies, leaving one of his henchman to eliminate Jack. When Jack kills the thug who was supposed to kill him, the sociopathic Cox's plans are ruined. Jack must race against time to get his family back before Cox and his fellow thugs carry out their murderous plans.
