Gail Fernhill, newly appointed of principal of Queen Anne's Girls' School in Dunedin, New Zealand is haunted by her past but befriends new property manager Neil Goodall. Neil pierces her reserve to support and help her when he discovers that as a teenager, she killed her abusive father in self-defence.
However, the case is reopened after the discovery of her father's rifle.
Inspector Peter Carrington attempts, by fair means or foul, to build up a
murder case against Gail and directs Tania Brogan, an undercover police
officer employed by the school as a teacher, to find evidence. However,
after an accident involving a bus load of pupils on a ski trip Tania switches her allegiance to help Gail but unwittingly plays into Carrington's hand.
Is Gail's successful life as a principal about to be cut short by her past?
