'Hello Niklas Sockenberg. We hope you have been satisfied with our services during this time, which has now reached its end. You have 14 days, 1 hour and 12 minutes left to live'

It is December in Stockholm and Sweden's Minister of Justice is under threat. An anonymous note has told him he has four days left to live. At the same time, a human skeleton is found in the Stockholm subway, belonging to a high-ranking financier.

Police inspector Mina Dabiri's team, still recovering from the traumatic incident last summer that ended in the death of a colleague, calls in mentalist Vincent Walder to help with the case. For Vincent, it feels as if the world is increasingly closing in on him.

When another pile of bones is found underground, the group is once again put to the test – what is going on in the tunnels deep under Stockholm? And who taunting the minister?
