An ambitious journalist, Janne Vuori, receives an anonymous letter calling on him to investigate the activities of a major company. It’s his chance to make a name for himself, and he decides, no matter what, to get to the truth. The case takes a new turn when the company’s executives start dying one after another as the result of suspicious accidents. It seems to be the work of a clever and ruthless killer. But who does that killer work for? The deeper Janne plunges into the investigation, the more questions he has. Who is hunting Janne and sending threats letters to his family? Are his unknown informants setting him up? And is it just a coincidence that he meets his father—the one who left them with his mother thirty years ago?
