South KOrea, 1948. Najin and Calvin Cho, with their young daughter Miran, travel to the US. Wary of the challenges ahead, they make the difficult decision to leave their other daughter, Inja, behind.

But then war breaks out in Korea, with no end in sight. Miran grows up in American suburbia, as Inja grapples in her war-torn land with ties to a family she doesn't remember. Inspired by a true story, The Kinship of Secrets explores modern Korean history, the cruelty of war and the power of hope.
