Ich muss dir was sagen

The twins Oskar and Leo are a lively pair of brothers aged four. But Oskar has been deaf since birth. The film follows the boys' family over a long period of time and touchesingly shows the everyday challenges that come with living in sign language. Martin Nguyen built a close personal relationship with the family during filming, which gives him a really intimate and emotional take on deafness.
