We don't talk about sick or healthy people at St Patricia's. Words such as hysteric, lunatic, and psychopath... They are no longer used. Because who amongst us can say that we are always healthy? An underground passage leads from the Dell nursery to Saint Patricia's asylum. Only the children enter, leaving their minders behind. On the other side are their parents - some of the most dangerous psychopaths in the country. Jan has just started working at the nursery. He is a loner with many secrets and one goal. He must get inside the asylum.... What is his connection with one of the inmates, a famous singer? What really happened when a boy in his care went missing nine years ago? Who can we trust when everyone has something to hide?
