Due to rigid teaching approaches and violation of the basic right to use sign language, the education of deaf children has left them with life-long consequences. Heartbreaking personal testimonies reveal how the ban on using their mother tongue in education has had a disastrous effect on the deaf linguistic minority. As a result of the linguistic genocide lasting a century, all conditions for the final extinction of Slovenian Sign Language were established. With the help of its representative disability organisation and the local deaf and hard of hearing societies, the deaf community became united in its efforts to prevent this from happening. The documentary presents one of the longest, but also the most important endeavours of deaf people to have their right to use sign language set down in the Slovene constitution.
