In the mid-1960s, Claire, a young woman in her early 20s, is sent by her parents from the Walloon province to economically booming Cologne to learn German better and attend a business school. She finds lodging with Hans, a philosophy doctoral student who travels a lot and therefore sublets his flat.
Claire soon makes the acquaintance of her neighbour, the open-hearted Mathilda, who is a dressmaker. Mathilda speaks French very well because she admires the French fashion world and dreams of going to Paris. She, unlike Claire, dresses fashionably and a little ahead of her time. Although she is still quite young, she confidently pursues her goals. The two women become friends and Mathilda encourages Claire, who enjoys the closeness and attention of her new friend, to perhaps resume her former dream of becoming a writer.
After an evening with Mathilda and her friends, Claire realises that she feels more than friendship for Mathilda...
