A father and son ride the New York City subway together—over many years and countless stops—as they navigate the shifting tracks of belief, responsibility, and love. What begins as a simple childhood adventure becomes a profound journey through memory, faith, and the struggle to pass on what is good in a broken world. Told with humor, intimacy, and aching honesty, The Second Avenue Subway is both a family story and a meditation on legacy—what we inherit, what we question, and what we hope to leave behind.
