The film takes us into the large Sedláček and Půlpán family, where the only hearing members are their children - CODA. In the 1980s, the term CODA was coined for these children, which is an abbreviation for Children Of Deaf Adults - loosely translated from English as hearing children of deaf parents. The main protagonist is a sixteen-year-old hearing girl, Jolanka, who lives in the shared custody of her deaf parents. She is trying to find her place in a world that consists precisely of the hearing and deaf world. The documentary shows how Jolanka copes with this specific environment and searches for her own identity, her place "in between" these two worlds. We follow her daily life full of challenges, obstacles and joys, whether she is in hearing or deaf world. I am CODA brings viewers a unique insight into the lives of family members from two different language cultures, a view of their communication in spoken and sign language. All of this leaves us with a deep awareness of the power of the human spirit and a desire to understand all those who share their worlds with us.
