A rogue grizzly is blamed for the deaths of cattle along the border separating Glacier Park and the Blackfeet Indian Reservation. The repetitive nature suggests to Coleman Broderick, the Chief Park Ranger, that the mutilations are ceremonies of a cult squatting on a ranch called Satan Dance- maybe the next mutilation will be a person. When Park Ranger, Henry 'Twobob' Roberts, discovers two bodies on the rugged trail into Otokomi Lake, the mutilation similarities are obvious. The companion of the dead hikers is missing and after a third mutilated woman is found in an isolated fire lookout tower, the search for the lost hiker in Glacier Park becomes a deadly tangle of circumstances. FBI Agent Cretcher takes over the search, pursues his own vendetta and accuses Coleman of raping and murdering the woman in the fire tower. The rumor at the Dirty Shame Bar is that the FBI, using the lost hiker as a cover, is searching for something more clandestine. Despite the County Coroner's suggestion that all three hearts were harvested before the mutilations, Henry fabricates a blackmail scheme with Agent Cretcher and risks his life to kill a rogue grizzly to be blamed for the deaths. Even if he is successful, Henry knows that the heart hunter will still be alive- and hunting him.
