Mary Tobin, a pretty, young historical preservationist, sets out for a long weekend of hiking and relaxation with her boyfriend of one year, Kent Summers. Everyone wants Kent to propose to Mary. When she visits her family before they take off, she visits her Grandpa, who is sick and near dying. It is clear Mary is very attached to him, more so than she’s been with her family as of late. At the lodge, Mary and Kent hike up the mountain and find a little girl, Charlene who has gotten stuck.
