Glittering Hands (2015)

Original title: 반짝이는 박수소리

Despite being deaf Sang-kuk never forgets to smile while he makes furniture. Kyung-hee can't hear either but with her natural beauty and outgoing personality, she enjoys her job at a sign language interpretation center. Between them they have hearing daughter Bora who is a director and a son named Kwang-hee. When, after moving eight times since marriage, Sang-kuk wants to move one more time, Kyung-hee opposes him. In filming the silent world of her parents, the director discovers new stories coming from herself, who grew up moving back and forth between two worlds-one of silence and the other of sound.
