om and Suze, two nineteen-year-olds both dreaming of the future, have sex when nuclear war strikes. Unfortunately, they then survive. Awkward. Cockroaches is a post-apocalyptic comedy about one family trying to survive in a wasteland of cannibals, perverts and one insufferable-ex. Our heroes struggle with boredom, fear and the ethics of cooking with their own body fluids.
