Nathaniel hears a scream, then the connection drops. Just moments ago, he was on the phone with a woman. An anonymous app connected them, and the woman was helping Nathaniel choose the right shirt, as he is blind. But the scream was unmistakable. What if something happened to the woman? He is convinced: it must be a crime. But no one believes him; there is no evidence, no trace. Together with a friend, journalist Milla, Nathaniel sets out to uncover the truth. He has no idea that he might be the only chance for the stranger – or her downfall.
