Homo Faber (Trois femmes)

A man turning 50 (Walter Faber) narrates his liaisons with three women: Hanna, who was pregnant and left him many years ago in Zurich; Ivy, who broke up with him recently in New York; Sabeth who is 20 and whom he just met on a boat to Europe. Sabeth and the narrator travel to France, Italy and Greece. But who is Sabeth? What does she feel towards the narrator? What does he feel towards her? The entire movie is shot in subjective view (we only see what the narrator sees); there are no dialogues, just his post-synchronised voice.
