A summer's evening in Amsterdam and two couples meet at a fashionable restaurant. Between mouthfuls of food and over the polite scrapings of cutlery, the conversation remains a gentle hum of polite discourse - the banality of work, the triviality of holidays. But behind the empty words, terrible things need to be said, and with every forced smile and every new course, the knives are being sharpened.

Each couple has a fifteen year old son. The two boys are united by their accountability for a single horrific act; an act that has triggered a police investigation and shattered the comfortable insulated worlds of their families. As the dinner reaches its culinary climax, the conversation finally touches on their children, and as civility and friendship disintegrates, each couple show just how far they are prepared to go to protect those they love .
