Episode 6 of Hijack begins with a startling revelation: Kai has managed to evade the cleaners for the moment, but the danger he faces is imminent and relentless. The Home Office has granted permission for the release of John and Edgar, yet their freedom is not without strings attached. British Counterterrorism has covertly hacked the GPS system of the vehicle assigned to the two terrorists, keeping a close eye on their movements.
Despite Edgar's firm assertion that they do not want to be tracked, three cars doggedly trail them. John and Edgar suddenly pull over, and Edgar exits the vehicle to hand Daniel a phone. From the confines of the car, he delivers a chilling message to Daniel, declaring that the agreement has been shattered, ominously hinting at the potential for bloodshed in the skies.
Meanwhile, Stuart, still reeling from the shock of Lewis's death, receives a cryptic message from Edgar. Jaime cautions against taking another life, but Stuart is obstinate, his resolve hardened by grief. Sam notices Stuart's unusual behavior as he unexpectedly draws the curtains closed in the cockpit and adjacent areas. Intrigued, Sam investigates and is horrified to find Stuart choking Deevia with a belt.
With calm determination, Sam manages to persuade Stuart and Jaime to snap a photo of the woman who was shot instead of committing another senseless killing. Jaime, her face hardened, threatens Sam and Colette to comply with her demands. Edgar promptly forwards the photo to Daniel, who quickly informs the others of the latest developments.
British Counterterrorism swings into action, deploying units to all potential airfields where the car could be heading. They are determined not to spook their quarry again, but the tension mounts as the clock ticks and Kai's precarious situation becomes increasingly dire.
Kai tiptoed cautiously on the first floor of his abode, ears pricked as he eavesdropped on the cleaners' whispered conversation. They spoke in hushed tones, yet the words they exchanged chilled his blood. "Sam is the one stirring up all the trouble," one of them hissed. "We have to stay put in this house and keep a gun to the family's head."
Sam, horrified by what he had overheard, quickly spread the news among his compatriots. He stood resolutely, feet firmly planted, and declared, "We must be vigilant and ready to seize the plane." He turned to Hugo, urging him to retrieve the scissors he had stealthily pilfered from the first aid kit. With trembling hands, Hugo obliged, and Sam set to work, freeing himself from whatever binds held him captive.
Stuart, sensing a disturbance, approached to investigate, but Sam's quick thinking and deft maneuvering allowed him to conceal his actions, keeping his hands clasped together to avoid suspicion.
Meanwhile, Felix Statton, an independent journalist with a reputation for unearthing the truth, received an invitation from a mysterious figure named Devilin. The meeting place was a dimly lit bar, where Devilin revealed a bombshell of information. Two prominent FTSE 100 companies, Kingdom Airlines and Macmillan Doyle, were poised for a seismic shift in their stock prices. Devilin hinted darkly that the shares would plummet once Felix broke the news of a hijacking. It was a tactic Felix had used to his advantage in the past, during a gas scandal that had rocked the nation. But this time, Devilin's intentions were far from honorable. He threatened Felix with insider trading charges, leveraging his knowledge of the journalist's past to coerce him into publishing the story within the next thirty minutes.
Sam, meanwhile, spied a phrase printed boldly on a tetra pack of a popular drink: "Get ready to shake things up." He saw it as a rallying cry, a signal to the passengers on the plane that they were about to take action against the hijackers.
The episode's title echoed in Secretary Neil's voice as he advised caution, urging a "slow compliance" that would give Flight 29 every chance to land safely before John and Edgar strayed too far from the path of righteousness. But fate had other plans. Edgar and John encountered an obstacle that was neither manufactured by authorities nor a trap set by the terrorists. It was a genuine accident, yet the terrorists' paranoia led them to believe otherwise. Edgar warned Daniel of the dire consequences that would ensue if the situation was not resolved swiftly and smoothly.
Kai tiptoed cautiously through the house, managing to reach a ground-floor room where he frantically attempted to contact emergency services. However, due to his whispered pleas, the operator struggled to make out his words. Fortunately, the situation was eventually resolved, and reinforcements were dispatched to the residence.
News of the hijacking swiftly spread, reaching every passenger on the plane. They all received Sam's urgent message and braced themselves for action. Meanwhile, the terrorists on the ground took an unexpected detour on a dirt road, surprising Daniel and Zahra. The FPCC speculated that they were heading towards a nearby airfield.
Edgar urgently messaged Stuart to send another photo. Amidst the chaos, Jaden managed to catch the Tetra pack at the rear of the plane. Stuart immediately recognized Hugo holding the pen in his mouth and zeroed in on him. However, Sam stood up and bravely took responsibility.
Louise and Neil engaged in a heated debate over what to do with the fleeing terrorists, who had chartered a plane to flee the UK. Suddenly, Louise changed her mind and ordered the special forces to withdraw, but it was too late. They apprehended the terrorists, but to the utter astonishment of the team, it was revealed that the men in the vehicle were not the actual terrorists. They were decoys planted in the car during a brief stop midway. John and Edgar had already escaped and taken a new vehicle.
Stuart lost his composure on the plane upon receiving the message, and a tense silence descended upon the cabin. He grabbed a female passenger by her hair and dragged her to the front of the plane. Sam leaped into action, grabbing Stuart from behind and engaging him in a struggle for the gun. Robin prepared to lock himself in the cockpit, while Terry was held captive by the ex-criminal, who appeared more nervous than anyone else on the plane. Shockingly, nobody came to their assistance.
Even more startlingly, a woman locked herself in a secluded area of the plane and revealed a gun hidden in her purse. She calmly took the weapon in hand and marched forward. Without hesitation, she shot Robin in the head and barricaded herself in the cockpit.
