Oliver Faulstich is 37 years old. He treads the line between people who are deaf, and those who can hear. When he was 15 years old, he fell ill with a rare form of meningitis. He lost his hearing from one day to the next. A shock for the teenager - and for his parents, too. Thanks to the modern technology of cochlear implants and a lot of training, he can now lead an almost unrestricted life again, as a family man. But everyday life remains exhausting. Now, he campaigns for people who find themselves in situations similar to his own.
