Seoul, South Korea. Mia is an outsider. The child of an English mother, she defies the rigid expectations of her Korean stepmother to work as a translator at the British Embassy. Her uncle runs a charitable - and controversial - school for North Korean defectors, and prevails upon Mia's stepmother to shelter a traumatised young student. Mia is too preoccupied to note the defector's strange behaviour - or its implications.
She has become infatuated with Thomas, a diplomat with a self-destructive streak. When an outrageous indiscretion endangers his position, it is Mia who saves him from humiliation and rescues his career. And the boundaries between them are crossed.
As a reward for his reformation, Thomas is commissioned to audit security amongst Embassy staff. Learning of Mia's connections to the defector, he is compelled to dig deeper into the life of the woman who has captivated him. Suddenly, all that Mia has done to get close to Thomas begins to cause her undoing.
