Luke Distang, wanted by U.S. authorities for the murder of his addled mother, is hiding in plain sight in Paris as a street sweeper. Lacking the skills to assimilate, he relies on three troubled women for survival and companionship: a young sculptor; an Algerian radio dispatcher; and a teenage runaway. Meanwhile, a bounty hunter, Nikolas Zaro, has picked up Luke's trail and is intent on bringing him to justice. Luke's father was convicted of the murder in Luke's absence. When Zaro meets Luke, however, he begins to doubt he has the right man. French anti-terrorism police close in as well, based on their own misinformation. With pressure building, Luke is forced to confront serious matters of character: Is he capable of saving someone other than himself? Is Zaro an enemy or an alter ego? And how much of his own identity can he surrender before he ceases to exist altogether?
