On 28 April 1995, the collapse of a viewing platform at Cave Creek, in Paparoa National Park on the West Coast, caused 17 students and a Department of Conservation Field Centre manager to plunge 40 metres into a chasm. 14 died, and four were injured. The documentary (from which NZ On Screen has three excerpts) explores what happened and why, with accounts by family members, survivors, and DoC staff. Made three years after the tragedy, the programme looked at its lasting impact on those left behind. It won Best Documentary at the 1998 NZ Television Awards.
