CIA NOC operatives Matt and his pregnant fiancée Emily are tasked by their superior and friend Chuck to secure the Industrial Control Systems (ICS) – a device that can control any electronic system, from the Polish KGB agent-turned terrorist Balthazzar Gor during his children's grandiose birthday party. They manage to steal the device, but narrowly escaped death from the plane crash when the flight crew–revealed to be under Gor's payroll to retrieve the device, ambushes them on the return flight. Realizing someone must have fed the flight crew information of their Key, the pair decide to go off grid.
Fifteen years later, the now married Matt and Emily reside in Atlanta under new identities while trying to care for their children Leo and Alice. They spot Alice inside the nightclub but are forced into a brawl when Alice's club-going friends becomes aggressive. Their actions became a viral sensation and attracted the attention of both Chuck, and Gor's Polish–Belarusian mercenary group Volka, who shoots Chuck while he attempts to warn Matt and Emily.
Matt and Emily briefly loses Volka's mercenaries, allowing them to take the children from school to escape from Atlanta onto a flight to England, where Matt had hidden the ICS Key inside the manor belonging to Emily's estranged mother, former MI6 sniper, Ginny Curtis. Arriving in Heathrow, the family is again pursued by Volka, as well as the MI6, led by Emily's ex-boyfriend Baron. While they had hidden their former identities from their children, the couple are forced to reveal the truth to them once they witness their parents fending off Volka's mercenaries and evading the pursuing MI6.
When Matt and Emily find the ICS Key, Volka's mercenaries raid Ginny's manor. Ginny fends off against a few of Volka's operatives, but her partner Nigel is injured. Chuck arrives, revealing that not only he faked his death, but also is working with Gor and Volka as revenge against Matt and Emily for losing his job as a direct consequence of them being presumed dead by the CIA for going off-grid. Matt and Emily are forced to surrender the ICS Key to save their kids, but they are knocked out and Chuck's Volka operatives take Leo and Alice anyway.
Using Leo's smart ring, they track them down to a black-tie event in Tate Modern, London, where Chuck plans to sell the ICS Key to the highest bidder. As a demonstration, his tech assistant Daphne uses the Key to hack the power station to trigger a brief blackout across London, as well as the Thames Barrier to forcibly open its floodgates. Matt and Emily infiltrate the museum, knocking out Chuck and Gor's guards while searching for their children.
The couple are followed by Baron and MI6, who also arrive to apprehend Chuck. While Baron's agents subdue the Volka operatives, the couple, with assistance from Ginny, pursue Chuck. He intends to escape London with Leo and Alice through the Thames Barrier. Nigel spots Daphne and crashes his van into hers, rendering her unconscious and securing the ICS Key. Ginny guides Nigel to close the Thames Barrier while Emily commandeers a boat, and she and Matt catch up to Chuck. Leo and Alice jump into the water, as Emily and Matt subdue Chuck. They leave him on the boat as it crashes into the now closing barrier, presumingly killing him.
Rescued by both the police and MI6, the family rest in relief as they reconcile with Emily's mother. As the entire family attends Alice's soccer game, Matt and Emily are met by Baron. He informs them that Chuck's body has never been found, suggesting he may still be alive, and proposes they recruit Emily's father, whom Matt is unaware of.
