Blade Runner is set in Los Angeles, 2019. Science has advanced so far we can now create artificial humans, known as replicants. These replicants are used for slave labour off-world and given their strength come along with some severe restraints; they have a four year lifespan and a whole police division, known as Blade Runners, exist to hunt down any escapees. When four of the latest batch of replicants, the Nexus 6, escape, Blade Runner Rick Deckard is tasked with hunting them down. Here's where the film picks up, with the first half seeing Deckard successfully take out two of the Nexus 6 and meet Rachael, a replicant who is blissfully unaware of her artificial origins. While this is going on, Roy Batty, the leader of the renegade replicants, tricks lonely genetic designer J.F. Sebastian into taking him to his creator, Eldon Tyrell. Realising his "father" can't lengthen his life, Roy gruesomely murders him. Investigating the attack, Deckard goes to Sebastian's apartment, where he and Roy engage in a gruelling fight that sees fingers snapped, hands nailed and walls head-butted. At its climax, Roy saves Deckard from certain death, delivers one of the best soliloquies in cinema history and dies. Deckard returns home and decides to run off with Rachael. The final scene of the film sees him spot an origami unicorn, the calling card of fellow Blade Runner Gaff. If you were confused by what was actually going on in the movie that should bring you up to speed. The plot is motivated by both Deckard's hunt of the rogue replicants and Roy's search for "more life", which both tie together in the ending.
