Best friends Mary-Ann (Foster) and Sandy (Thompson) are finally taking their dream expedition to New Zealand. They are accompanied by their teenage daughters Jaretha (Gillette) and Kerry (Nicoll). Issues of first night frights from the local wildlife and daughters that can't stand each other become insignificant when they come face to face with Kiwi poachers. No match for gun-toting guys, the four find themselves held prisoner and fearing for their lives.
Unfortunately the movie Lost Valley is not yet available on HBO Max.
