SAM and HANNAH, husband and wife and starship engineers, are shipwrecked on a long-lost space station, the “Jack”. Shaken by “pod-quakes”, they discover it’s antiquated, crumbling, and ready to fly apart. Local humans are pre-industrial, xenophobic, and fighting aliens so, only the two engineers can fix the place. Dodging feuding factions and rogue robots, they struggle to repair the escalating damage with patchwork solutions. It looks hopeless - until Space Marines invade, declare martial law, and trigger disaster. With the “Jack” shaking to pieces, and everyone hunting their heads, Sam and Hannah cobble a last-ditch plan with “one little hitch”: everyone cooperates or everyone dies.
