John Harper, haunted by his past as a mercenary, seeks refuge in a solitary hut on a tropical Indonesian island. Night after night, haunted by fears that his violent history has found him, Harper encounters Rita, a woman scarred by her own traumatic experiences. As their affair intensifies, so too does the risk—as both Harper and Rita grapple with the shadows of their former lives. 'Black Water' intricately weaves between the complex tapestry of Cold War Europe, the Civil Rights movement in California, and Indonesia's 1965 massacres and its subsequent dictatorship to narrate a deeply personal journey shadowed by historical atrocities. Can two damaged souls find redemption in each other, or will the repercussions of their past actions prove too perilous?
