Lost Valley (1998)

When Mary-Ann Compton and Sandy Franzetti from Los Angeles fulfill their childhood dream of a journey through New Zealand's countryside in a motor home, it turns into a nightmare. Not only do their teenage daughters, computer-geek Kerry and fastidious Jaretha, not get along at all, they also get lost in the bush and are suddenly attacked and hunted for by two poachers. So the four women will have to learn to team up and fight back the evil forces.
