It's a case like no other, with a trail of allegations dating back 40 years.
Nearly two hundred people claim to have been abused as children at Lake Alice psychiatric hospital in rural Manawatu in the 1970's.
The disgraced doctor at the centre of these allegations, Selwyn Leeks, has never been brought to trial.
But there is some hope on the horizon, as the United Nations committee on torture is considering the complaint of one of the survivors.
The committee can then make non-binding determinations on whether New Zealand adequately responded to what happened at Lake Alice.
Newshub Nation has investigated for the past three years to uncover why, decades later, the survivors are still waiting for justice.
