Alexander the Great dies in Babylon in 323 BC at thirty-two, and the ancient accounts do not agree on why. Plutarch and Arrian describe a fever that set in after heavy drinking with the admiral Nearchus and a friend, Medius of Larissa, worsening over fourteen days until Alexander could no longer speak and only raised a hand as his soldiers filed past his deathbed. Diodorus Siculus instead has him collapsing after downing a bowl of unmixed wine in honor of Hercules. The film weighs these against modern diagnoses, malaria, typhoid, poison, against the record left by ancient historians, then follows the stranger mystery of what happened next: his body became a pilgrimage site venerated by emperors, and within a generation its tomb vanished from Alexandria entirely. With no archaeological trace left to dig up, the case rests on eyewitness accounts from visitors to the tomb, and on one historian's argument that Alexander's remains survive today, renamed and enshrined as a saint in a Christian basilica.
