Pachinko follows one Korean family through the generations, beginning in early 1900s Korea with Sunja, the prized daughter of a poor yet proud family, whose unplanned pregnancy threatens to shame them all. Deserted by her lover, Sunja is saved when a young tubercular minister offers to marry and bring her to Japan.

So begins a sweeping saga of an exceptional family in exile from its homeland and caught in the indifferent arc of history. Through desperate struggles and hard-won triumphs, its members are bound together by deep roots as they face enduring questions of faith, family, and identity.
