At the end of World War I, Ferdinand, a civil engineer, is entrusted with building Dunkirk’s new port. The trench’s darkness are thus followed by the light of the coast and the wonder of an encounter with Clémence. A tale of a time through love, their story takes place through a montage of photo and film archives as well as present-day images of the settings and their dialogues brought to life by actors. A sensorial exploration of places and bodies, this film reveals the eternal beginning of love, but also recreates the strong sense of a present, which will inevitably become a past memory.
