As the Football World Cup is taking place in Italy, Rome is flooded with supporters; the traffic is chaotic and French-born Marie Christine, who works as a translator, finds a bag that belongs to Miriam, who must leave the next day. Marie Christine decides to find her to return her passport, but one Giuliano Ferrini tries to prevent this. So Marie Christine finds herself navigating through a hot Roman night in a city she doesn't know, among people she never dreamed could inhabit the same city.
