Buzz Bissinger’s twins were born three minutes—and a world—apart. Gerry, the older one, is a graduate student preparing to become a teacher. His brother Zach is a savant, challenged by serious intellectual deficits but also blessed with rare talents: an astonishing memory, a dazzling knack for navigation, and a reflexive honesty that can make him both socially awkward and surprisingly wise.

One summer, striving to understand the twenty-four-year-old son who remains, in many ways, a mystery, Buzz convinces Zach to join him on a cross-country road trip. As father and son drive from Philadelphia to Los Angeles, revisiting all the places they have lived together, Buzz learns to see the world through Zach’s eyes. Father's Day is a powerful account of this journey, and a universal tale of the bond between parents and children.
