Little Steppington is a small suburb that should be calm, cozy and quiet. But it is not lucky with its inhabitants. Instead of quietly killing time knitting, they kill each other. Vegetable cutters and large-caliber weapons go into action. Under the guise of a women's charitable society, classes of yoga and a circle of amateur runners, secret super-agents hide themselves, ready to eliminate a couple of competitors for the sake of another injection of Botox. Feeding their husbands an industrial dose of Viagra for breakfast and turning a quiet British suburb into a kind of slum where policemen do not go.
