It has been nearly three decades since the outbreak of the rage virus; Britain is under quarantine, where isolated communities cling to life amidst the ever-present threat of infection. One such group lives on an island connected to the mainland by a single, heavily defended causeway. Among them are Isla (Jodie Comer), her husband, Jamie (Aaron Taylor-Johnson), and their son, Spike. When Isla falls ill, Jamie embarks on a perilous journey with Spike to find a doctor on the mainland. As they navigate this treacherous world, they encounter Dr. Kelson (Ralph Fiennes), a survivor with his own secrets, and Sir Jimmy Crystal (Jack O’Connell), a cult leader whose intentions may be more dangerous than the infected. The journey tests their resilience, revealing the depths of human desperation and the enduring hope for salvation.
