In a near-future metropolis wracked by corporate intrigue and clandestine warfare, two parallel narratives unfold across 2085 and 2086. Metropolitan Police agent Amano Elle pursues a foreign spy into a black-site facility where classified nuclear research has been conducted, only to cross paths with Alina, a hacker from a rival nation, each hunting for dangerous secrets buried beneath layers of institutional deception. Simultaneously, construction worker Sarah O'Connell finds herself thrust into a desperate fight for survival when rogue machines turn the Highrise multiplex into a war zone, forcing her to don a combat suit and uncover the shadowy forces orchestrating the chaos. As these separate investigations spiral outward—touching on weapons development, military conspiracies, and radical bio-engineering—the protagonists must navigate a web of competing agendas to expose the truth before it's buried forever.
