After 28 weeks of deadly terror, Britain is empty. As a result of the loss of the vector, the virus died out. With the landing of a transport plane from the United States, Britons who left Britain before the outbreak returned to land that had been ravaged by the virus for half a year. It can be said that this is the last group of British people on earth, and the burden of rebuilding their homes falls on this group of civilians. However, shortly after the reconstruction work was carried out, survivors of the virus infection were reported. Scientists also hope to extract serum from survivors to develop a vaccine against the virus. However, what we never expected is that the virus has not died out as people think, but has become more powerful after evolution. The last group of people in the British Isles will face an unprecedented crisis.
