Grieving Museum curator Margaret returns to her childhood home to leave behind her sister Shirley’s ashes and attend the final reading of her will. Unbeknownst to Margaret, Shirley has left her eight million dollars and a letter asking Margaret to return to its former glory an abandoned railway line–a fanciful notion, everyone tells her, with no real legal binding. Embarking on an adventure that will test more than just an executor’s duty and loyalty to her sister’s legacy, Margaret is forced to make decisions now and for the future that will challenge and forever change a landscape, her career, her marriage, her friendships, and her very own legacy.
