An unlikely ensemble of hikers meet on the Appalachian Trail, each carrying a secret. One has an uncertain memory of a violent incident; others are hiding fears, unrequited affections, failing health, rejection, and crimes committed or planned. And then there's Beeline, a stray cat who offers comfort and clues. Each follows their own adventurous path to the Fourth of July festivities at the Thirdway Lodge-and the inevitable fireworks.
