Establishing shot of an expensive mansion. Armed guards, some with dogs, patrol the grounds. Think True Lies.
Two guards are patrolling together, passing under a tree. They have a dog with them.
The dog is being pulled into the air via a long garrote wire around its neck. The guards are staring in shock.
Close up on one guard, holding his neck. We can see a ninja star protruding from between his fingers. Blood is spraying from the severed carotid artery.
Close up on the other guard. He has his radio to his mouth, about to speak. He looks terrified. Behind him, in the darkness, we see two black glistening eyes and the shine of a blade approaching the man's neck.
Wide shot, showing the dog hanging dead from the tree, the first guard dead on the ground, and the second guard on his knees, clutching at his slashed neck, his hands and clothes already soaked in blood. There is no sign of their assailants.
