A burnt out cop is ordered to hunt down and kill four escaped replicants that have come to earth to extend their lives.

This is probably one of the best SF movies made. Ridley Scott's masterly vision shows just how good a director he really is. The story (though simple) is compelling and keeps the viewer glued for the entire running time. The entire cast (especially Rutger Hauer) all make a wonderful job of their roles. This movie is already been classed as a 'classic' and as more time passses (I feel) it will be ranked in the top five influential movies made.
