In a near-future scenario marked by geopolitical tension between Western nations and China, the UK Ministry of Defense is developing a brain implant for injured soldiers. Dr. Vincent McCarthy, an expert in artificial brain transplants, works with his colleague Lucy on an experimental procedure to revive Paul Dawson, a soldier who died two years prior. After the procedure, Vincent is disheartened by Paul's cognitive abilities, leading to a heated debate about whether to continue the experiment. Suddenly, Paul, now partially revived, unexpectedly attacks Vincent, thrusting a pen into his chest and causing chaos in the lab. This incident raises profound questions about identity, the nature of life, and the ethical implications of such technology.
