The premise sounds strange. It is set around 2020, in a Los Angeles where a homogenized Asian culture has pretty much taken over. The Tyrell Corporation started making these things called "replicants" - they're pretty much people only robots. The only way you can tell them apart is by asking them a whole load of questions and then waiting for their eyes to flash or something. Replicants soon started getting creepy, and, like, growing emotions after a little while, so Tyrell built in a self-destruct after four years. All the replicants were sent to be slaves because that's pretty much the best reason I can think of to build such robots. When they escape to Earth, they get a blade runner such as Harrison Ford (Rick Deckard) to beat them down, hence the title.

The catalyst is that four really advanced and dangerous replicants escape to Earth, supposedly in an attempt to fix that whole self-destruct thing. Meanwhile, creepy freaking Tyrell keeps building and improving on the replicants, even though they already didn't work out. He makes Rachael (Sean Young), who is almost indistinguishable from a human, even to herself. Deckard falls in creepy love with Rachael and they end up having creepy cyborg/rapey sex in the middle of the movie. Yeah. But it's good, I swear.

The end confrontation between Roy Batty (Rutger Hauer), the main escaped replicant, and Deckard is too amazingly amazing for me to divulge any info, save for this tidbit: he ends up both shirtless and pantless by the end. Yeah. So go out and buy it. Yesterday.
