In the near future, Canada is at war with Quebec, battles are determined by television ratings, and weapons are sponsored by McDonald's and IBM. In the midst of social chaos, a lesbian couple, Barb and Alex, dress themselves in protective masks, gowns and rubber boots to spend a quiet afternoon at the zoo. Barb is gang-raped by soldiers while taking a short cut through a restrictive zone. Fearful of infection, Alex begs her to take an AIDS test. With a world imploding around them, Barb decides to announce her result as the punchline of a comic routine. At first, Alex can't see the joke, but she eventually joins in and engineers an attempt to make love without touching.
