Chea Samy was a renowned soloist in Cambodia’s royal dance ensemble in the 1930s—and Pol Pot’s foster mother. After marrying his older brother, she raised him as her own until he vanished into the underground. In 1975, like millions of Cambodians, she was forced into labor, only realizing years later that the boy she raised was the Khmer Rouge leader. One of the few dancers to survive, she returned to Phnom Penh to teach, preserving traditional dance. Her student, Sophiline Cheam, now a successful choreographer, explores Cambodia’s past, including Pol Pot’s little-known connection to classical dance.
