Melanie Fraser has a problem. Her mother, Dr. Janet Fraser, thinks that she can bond with her stepfather by accompanying mom and dad on a simple business excursion to see if a small tour guide company is a good investment for clients. The fact that the trip will take the threesome to the site of a volcano in New Zealand is nothing for Melanie to worry about.

Mount Extreme decides to live up to its name just in time to make Melanie's quality time with the folks seem like a big mistake.
