South Africa in the 1880s. A young and naive English doctor by the name of William Abbey witnesses the lynching of a local boy by the white colonists. As the child dies, his mother curses William. William begins to understand what the curse means when the shadow of the dead boy starts following him across the world. It never stops, never rests. It can cross oceans and mountains. And if it catches him, the person he loves most in the world will die.
