When ticket inspector Georges Turmes first meets Yamina Ben Khouri on the train between Luxembourg City and Bettembourg, she is just another passenger. When he sees her again, she is trying to sleep between some old petrol barrels and an abandoned garage near the railway station. When they run into each other a third time, she is trying to hide in the train toilet, severely beaten up, blood all over face. Georges offers her help, and she accepts, reluctantly--and both their lives will change forever. Then Yamina disappears, leaving Georges completely disoriented. Trying to find her, Georges meets her old acquaintances. The more of them he speaks to, the less he seems to know about her; everybody has a different version of her life. Finally, he is convinced he has to go to Algiers to rescue her.
