Leading a tour down the rapids outside Aspen, Colorado, whitewater guide Dani Whalen comes upon the dead body of a close friend. Trey Watkins's death is ruled an accident. Finding evidence that seems to back up her suspicions that it wasn't, she takes her case to Wade Dunn, the local police chief and her ex-stepfather, with whom she shares some unresolved history. Wade insists the case is closed, but Rooster, a hot air balloon operator in town, claims he saw something from the air she should know. When he suddenly dies in a fiery crash, Dani threatens to take her suspicions public, goading Wade into tossing her in jail.
