Kept on a short leash through a volatile mixture of indoctrination, misinformation and fear, three grown-up siblings--two sisters and one brother--find themselves confined to their lavish, isolated villa. As a result, holed up in their beautiful, high-walled prison, the siblings rely on their cold, manipulative parents to learn about the ways of the world, taking reality-defying lessons from instructional cassette tapes. And, as the cruel patriarch and his frigid wife deliberately keep their unsuspecting, submissive children in the dark, freedom is nothing but a word. Then, a bad influence in the shape of security guard Christina enters the equation, and suddenly, sweet, baffling temptation threatens years of meticulous mind-programming. Is the grass greener on the other side of the fence? With this in mind, how can an ordinary dogtooth stand in the way of happiness?
