Two victims trapped. Only one way out: kill or be killed.

Two young people are kidnapped and held captive at the bottom of an empty swimming pool from which escape is impossible. Beside them, a pistol loaded with a single bullet and a mobile phone with enough battery to deliver a terrible message: "You must kill to live." Days pass, hunger and thirst intensify, anxiety mounts. Until the fatal outcome.

The kidnappings continue. These are the most perverse crimes Commander Helen Grace has ever faced. If she hadn't spoken with the traumatized survivors, she wouldn't be able to believe it.

Helen knows the dark sides of human nature, including her own; yet, this case and these seemingly unrelated victims leave her perplexed.

Nothing will be more terrifying than the truth.
