Two men retrace their steps along the Gironde estuary, cycling up from the ocean toward Bordeaux by road and path, each on a different bank. Christophe Goussard makes the journey in black-and-white images on the right bank, in the Blayais, his birthplace, while Christophe Dabitch tells it as a personal account on the left bank, in the Médoc, a place of family ties and childhood memory, the book alternating banks and chapters of text or image, with small colour photographs interspersed among the words like notes taken along the muddy waters of the estuary.
