The year is 2019. Replicants - artificial humans - are forbidden from returning to Earth, with the penalty of death for those who do. Yet, one day, some of these beings return. Possessing the strength and intelligence of several ordinary humans, this unique species is nearly indistinguishable from the real thing. They must be neutralized. Only one specialized unit has the ability to track them down: the Blade Runners. A breathtaking hunt through a futuristic world begins.
