| We love to play games with our children. But what happens when someone else starts to play with them too? Someone we don't know. Can't see. Can't hear. In The Whispers, someone or something -- is manipulating the ones we love most to accomplish the unthinkable. An unseen alien force has figured this human weakness out. They have invaded earth and are using our most unlikely resource to achieve world domination – our children. |
