Hunter gatherers

"Pam and Richard are hosting their best friends, Wendy and Tom, for their annual dinner get-together. An animal sacrifice kicks off the evening, followed by a little more sex, violence, deception, revelations, wrestling, and dancing than previous years. A darkly comic evening where the line between civilized and primal man is blurred, and where not everyone will survive long enough to enjoy the brownies for dessert"--P. [4] of cover.
