About
"A runaway train turned into a countdown clock"
A sleeper train from Glasgow to London becomes the target of a cyberattack, its systems hijacked while passengers remain unaware anything is wrong. A civilian with a hidden past ends up trapped aboard, forced to work with a control-room team racing against the clock to stop a collision. The show moves fast, cutting between the claustrophobic carriages and the tense hub trying to hack back, leaning hard into ticking-clock momentum rather than character depth. It's a brisk, plot-driven thriller built for binge-watching in one sitting rather than savoring.
the relentless real-time tension of a hijacked train nobody on board can stop.
you want deep characters over pure plot-mechanics and countdown-clock momentum.
