16 year-old Kelly Ann gives birth to a baby boy, which is immediately given up for adoption. Six weeks later, trying to get over the emotional upset, she goes on an overnight hike with her church youth group. The group is joined by 18-year-old Lee, the father of Kelly Ann's baby. Kelly Ann isn't pleased to see him. The rest of the group begins to worry when Kelly Ann starts thinking she hears a baby crying on the moors. But they do find a baby abandoned in a ruined castle. As they hike back to take the baby to safety, the group is stalked by a wild beast that picks them off one by one.
