Anni Korpinen, a middle-aged sales manager at a sauna oven company, finds herself as the implicated main suspect when her new boss is found dead in his sauna. As the body count rises, with her being implicated in each murder, Anni must race against time to clear her name. The dark humour from Tuomainen's "theme park" trilogy finds a new home in this medium paced bizarre psychological thriller, that has a tongue in cheek go at middle age and corporate Finland.
