On a visit to the US consulate in Frankfurt, the young son of former Special Forces soldier Sara (Jeanne Goursaud) disappears without a trace. Stranger still, nobody seems to remember him ever being in the building. Sara knows that the German authorities have no jurisdiction inside the consulate, and if she’s forced to leave now, she might never see her son again. Sara moves deeper into the labyrinth of the consulate, desperately searching for her son, unaware of the growing danger of a dark conspiracy around her.
