Prey

A carnivorous, shape-shifting alien lands in the woods of rural England. His mission is to evaluate the suitability of humans as a source of food for his species. He encounters Jessica-Ann and Josephine, a lesbian couple who live in a nearby manor house. Kator kills and partly devours two policemen who are examining the couple's abandoned car. The trio celebrate with a champagne party for which Jo dresses Kator in drag.
