Set in the not-too-distant future, THE LAST ENEMY follows mathematician Stephen Ezard (Benedict Cumberbatch) as he travels from China to his native England to attend the funeral of his brother Michael (Max Beesley), a relief worker who was killed by a landmine in Afghanistan. Upon his return, Stephen finds a world that has changed subtly but significantly from the one he left behind several years earlier. National security is tighter, biometric ID cards are compulsory, public spaces are monitored 24 hours a day, and armed police patrol the streets. Caught in the midst of a government surveillance scheme and the politics of global security, Stephen is forced to challenge his own complacencies about this new society.
