Khem looks into her father's history, Khun Srun, a Cambodian writer who joined the ranks of the Khmer Rouge in 1973 and was executed by them in 1978.
She meets some survivors, a cousin, an aunt and workers in a railway workshop who knew her father. At the same time, she and her two sons have to cope with the difficulties of a precarious life given that they are still living in a former Khmer Rouge stronghold.
In parallell with Khem’s deeds, the film enables us to hear the autobiographical and satirical voice of a humanist and pacifist writer who chose the revolutionary side (to his own detriment as it turned out). Inscribed in the present time of a country which is rapidly "developing" at the expense of a certain number of Cambodians, and in particular in a capital bristling with cranes, the voice of Khun Srun questions with acuity the contemporary Cambodia he never knew.
