Omniscient

Omniscient is set in the near future, in a city where every citizen is followed 24/7 by a tiny (almost imperceptible) drone. The machine feeds a super-computer with data, which no human is allowed to access. Crime rates are almost zero since the perpetrators know for sure they will be caught. The Omniscient System seems flawless until a young woman named Nina finds a murder but this crime is unaccounted by the system. It's up to her to figure out what it is hiding.
