Torchwood (2006 TV Series) - Season 4 - Episode 7

Season 4, Miracle Day (10 episodes, Starz/BBC One, 2011), shifts to a global scale. Overnight, no one on Earth can die; injuries persist but death stops, causing societal collapse. CIA agent Rex Matheson and analyst Esther Drummond track the word “Torchwood” to Jack and Gwen, pulling them into a transatlantic hunt for the source of the “miracle.” The season interrogates healthcare systems, detention camps, and corporate profiteering, revealing a blood‑line ritual tied to Jack’s immortality. In the finale, death returns, Esther dies, Rex is changed but survives, and Jack and Gwen part ways, closing this chapter of Torchwood.
