Jonathan is a private detective in a decaying eastern European city. He is drowning in his work, his failing marriage and the corrupt landscape that surrounds him. One day, he is approached by an elderly couple to investigate the disappearance of their daughter, who has been missing for nearly two decades. Troubled by the faded photograph of a little girl the couple press on him - the same age as his own daughter - he feels compelled to find her. Then one night, as he is contemplating his troubled marriage, he encounters a young woman crouched at the foot of a stone angel on the bridge spanning the river that divides the city, a woman who suddenly jumps into the icy water below. As Jonathan plunges after her he finds himself dragged into her ghostly world of confusion, coincidence and intrigue and the city he thought he knew becomes strange, mysterious and threatening.
