When the catastrophic Medusa virus incinerates humanity's future, the survivors encounter an apocalypse that razes cities and spirits. Among the few who resist this despair are Adam Fisher, who discovers a glint of hope in the devastation, Sarah Wells, a soldier wrapped in personal tragedy, and Freddie Briggs, a desolate ex-athlete mourning his lost family. In a wasteland scarred by viral fury and human fallibilities, they confront the vestiges of civilization and a new, predatory threat vying for dominance. 'The Immune' chronicles their desperate pursuit of sanctuary, meaning, and the faint echoes of rebirth in a world precariously hovering on the edge of oblivion.
