Stiff Upper Lips is a broad parody of British period films, especially the lavish Merchant-Ivory productions of the 'eighties and early 'nineties. Although it specifically targets A Room with a View, Chariots of Fire, Maurice, A Passage to India, and many other films, in a more general way Stiff Upper Lips satirises popular perceptions of certain Edwardian traits: propriety, sexual repression, xenophobia, and class snobbery.

It's an invasion of the most personal and terrifying kind. When a meteorite crash lands onto a Boston college campus and an alien beast is released, only one man understands its mission to mate. From the depths of an all girls college, the grotesque monster stalks his prey in a cat-and-mouse chase until the final conflict where only one species can survive.
