A married couple from the neighboring apartment embrace passionately in the building entrance. Mistaking their public affection for mockery of his single life, a withdrawn man plots revenge with a hypnosis device he found by chance. “When you wake up, you’ll want the man before you to impregnate you...” Thrilled by how well it works, he gets carried away, taking control of not only the wife but her husband as well and steadily invading their married life.
