Down River in Bloomington, MN

A honeymoon couple disappear while canoeing the St. Croix River. With visiting VIPs due in days and quick searches revealing no sign of the missing couple, U.S. Park Service Investigators Doug and Jill Fletcher are dispatched to the scene.
The Fletchers quickly determine the honeymooner's disappearance is not an accident and the search becomes more complicated than the simple rescue everyone hoped for. Jill and Doug are caught on the river as thunderstorms loom on the horizon. With lightning crackling around them, their canoeing skills are pushed to the limit.
