Your last words to your teenage daughter were, ‘Sleep well’.

By the next morning, she has vanished. Her bed not slept in, an unfamiliar phone in her place. Before you have time to catch your breath, it rings.

CALLER UNKNOWN
 
Someone has taken your daughter. They don’t tell you where. They don’t tell you why.

Only that you must do what they say to ever see her again. Do not contact the police. If you do, they will kill her.

You have a choice: do you risk contacting the authorities anyway?
 
Or, do you take the law – and your daughter’s life – into your own hands?
