Ghosts of Sugar Land examines the radicalization of a young American Muslim. Through interviews with his friends, the documentary tells the story of “Mark,” who converted to Islam before college and became radicalized shortly thereafter. A number of years ago, through Facebook posts, “Mark” stated that he crossed over from Turkey to the “Islamic State.” His friends from Sugar Land, Texas—all masked to protect their identities—hypothesize about what may have happened that led their friend to join ISIS. Ghosts of Sugar Land won the Nonfiction Jury Award for Short Film at the 2019 Sundance Film Festival.
