An attack on a bank locker in Brussels, Belgium, sparks a chain of events centered around Ben Logan, portrayed by Aaron Eckhart, an ex-CIA agent trying to reconnect with his estranged daughter, Amy, played by Liana Liberato. Ben works at Halgate Securities, a company known for designing advanced security systems for elite clientele around the world. During his tenure, he uncovers a critical security vulnerability within the company's electronic locking mechanisms. This breakthrough involves a simple household solution capable of rendering the locks useless.
In a pivotal meeting with senior directors, Ben presents his findings to emphasize the significant flaw in their security systems. He also raises a troubling point regarding the ownership of the patents related to Halgate's technology, highlighting that the firm seems to lack legitimate claims over its own systems. His supervisor, Derek, remains unfazed and instructs Ben to keep this information under wraps while he investigates further.
As the sun sets, Ben files a comprehensive report detailing his discoveries and leaves the office. However, his return the following day reveals an unsettling situation: the entire floor of Halgate is deserted, and all evidence of the company's existence has vanished. Accompanied by Amy, Ben races to the corporate office in Brussels, only to find no record of either of their employment. Frustrated and confused, Ben learns that he supposedly worked for a non-existent subsidiary on a product Halgate doesn't own, and his financial records offer no evidence of past payments.
Chaos ensues as Ben is kidnapped by Floyd, an acquaintance from his Halgate days who now seems to have ulterior motives. In a desperate struggle, Ben manages to eliminate Floyd but is soon on the run, with Amy urging him to involve the authorities. The tension escalates further when Ben discovers an Antwerp locker linked to Floyd, which contains sensitive dossiers on his colleagues. The grim truth strikes him as he finds out that many of these individuals have recently turned up dead, all of whom shared a similar immigrant background with him.
Their harrowing journey continues when they face an assassin at the local morgue, resulting in Amy being injured by a gunshot. As the situation spirals, Ben reveals his former CIA affiliation. At the CIA's European headquarters, his handler, Anna, navigates a tense situation where Floyd and the assassin were acting on behalf of the agency. To complicate matters further, Anna’s superiors suspect Ben of having lapses in judgment leading to his decommissioning six months prior.
The narrative thickens as Anna uncovers that the bank locker heist in Brussels held documents central to an ongoing investigation into Halgate by the U.S. State Department and Belgian authorities. This investigation revolves around a sunken merchant ship once owned by Halgate, embroiled in controversy due to illicit arms dealings, making Ben a suspect in the crime. Time ticks away as Anna seeks to locate Ben and clear his name.
In a twist of fate, Anna reaches out to Derek, who has unlawfully accessed the locker Ben had earlier breached. As she grapples with uncovering further twists in the plot, it becomes clear that Halgate's legal representation is also involved in the treachery surrounding Ben. Tensions rise when it is revealed that Ben has traced the patent of the security systems back to the CIA itself, leading to deeper conspiracies.
In a desperate search for Amy after her abduction by yet another assassin, Ben delves into the evidence he collected from Derek. These pivotal papers indicate the CIA’s complicity in Halgate’s underhanded dealings, drawing Anna into conflict as she realizes how deeply entwined they are. She makes a daring move to secure Amy’s release directly from Mr. Halgate, the very man behind the corruption.
The climax of the narrative sees Ben orchestrating an explosive finale during a high-stakes exchange involving the incriminating evidence. With meticulous planning, he rigs the briefcase, leading to a devastating outcome that claims the lives of Halgate, his lawyer, and the hired assassin. Ultimately, Ben and Amy triumph against the odds and make their way back to the U.S., leaving behind a web of deceit and danger.
