A young, female prison guard, works in a hopelessly overcrowded jail in Madagascar. Her observations of the realities of prison life interlace with her daydreams about her unknown father, who disappeared after murdering his own brother when she was still a child. Secretly hoping that one day her father will be washed up as a prisoner, she bypasses time by imagining his criminal career. In her fantasies, he becomes a mythical serial killer, who is obsessed with playing the dice to decide the fate of his victims. Her prison routine is suddenly torn apart when a new inmate arrives who claims to know her father.
