Harry, an African American, retired high school history teacher turned D.C. tour guide, decides to explore guiding opportunities in Guatemala. On an outing to Mayan ruins, the life-long bachelor with a rapport with teens, connects with Bryn and through her, with her ex-pat grandmother, Cobi. Surprised by love, so late in life, in a cultural setting that views him as a "darker wave in a sea of brown," he links up with Cobi as she unravels her tangled, exiled, Southern past.
