Antoine, a history teacher in his early 50s, learns that he has become very hard of hearing. Unable to own up to his handicap, he resigns himself to living in his bubble, even though his entourage finds his behavior increasingly odd. His encounter with Claire, widow and mother of a young girl who has stopped speaking, will lead him to open up to the world. 

When Pierre learns that his parents are not his parents, he wants to find out who he is and where he comes from. Raised in nature, Pierre has never been confronted with society. He does not know the codes. He will team up with Anna who will help him in his quest and cross a whole gallery of characters as funny as tender. But during his investigation, Pierre will lose his colors – like a photo that fades.
