Mother Lode

A couple of youngish adventurers go into the wilderness of British Columbia in search of a lost colleague. Their plane crashes and they find themselves at the mercy of a crazed old Scottish miner, who has lived in isolation for many decades searching the mountain caves for a chamber of long lost gold. He is prepared to do anything – including murder – to keep his gold for himself.
