Teenage twins Rachel (Sophie McBride) and Theo (Tom Cameron) travel to Auckland to stay with relatives following the sudden death of their mother. Where there was once a psychic bond between them, now there is a rift as Theo, particularly, refuses to confront his grief.
Staying with their Aunt Kay and Uncle Cliff on Lake Pupuke, the twins are fascinated by the volcanic lake and the smell that seems to come from the creepy old Wilberforce house around the shore. They visit Mount Eden, where Theo sees Mr Jones (Sam Neill), a strange old man from whose hands fire seems to glow. When it seems the twins are being watched, Theo resolves to investigate the Wilberforce house.
Based on the novel by acclaimed New Zealand author Maurice Gee.
