In the Fade, German director Fatih Akin’s new drama about tragedy, xenophobia, and weaponized grief, is split into three parts. First is “Family,” focusing on Katja (Diane Kruger), her Turkish immigrant husband Nuri (Numan Acar), and their adorable son Rocco (Rafael Santana). They live in a sleek, comfortable home and operate their own business in Hamburg, but their domestic bliss is annihilated when a targeted nail bomb kills Nuri and Rocco.
