A small family, parents Joy and Roger, and Emma the daughter are on a road-trip vacation in a motor home, when outside of an eastern Utah town, on a lonely back road, they come upon a body, apparently that of a bicyclist, ostensibly shot. As the authorities become dutifully involved, the three learn of the familial relationship between the deceased bicyclist and a nearby relative they just happened to be coming to visit. That relative's reaction to the news of the person's demise, the question of who pulled the trigger, and subsequent revelations of family secrets, past and present, provide a much more memorable family vacation than the three had ever anticipated.
