In the future, at an underground subterranean base, the United Kingdom only has a couple of weeks before the city of Taipei, Taiwan falls to the Chinese. The British need soldiers who are both fluent in Chinese language dialect as well as ruthless killers. Scientists employed by Britain's Ministry of Defence (United Kingdom) produce a Cybernetics implant that allows brain-damaged soldiers to regain lost functions. Scientist Vincent McCarthy sets up a Sally-Anne test for soldier Paul Dawson, a recipient of the cybernetic implant to rehabilitate his left hemispherectomy. Upset with Dawson's inability to remember anything about his past, McCarthy ignores Dawson's requests to see his mother. Dawson turns hostile, kills a scientist and wounds McCarthy, before apologizing and being shot. Afterwards, Dawson's mother regularly stays on the road to the entrance of the secret base, though McCarthy denies that her son was ever there.
