Jack reports to the Italian countryside, where he holes up in a small town and relishes being away from death for a spell.

But by stepping out of the shadows, Jack may be tempting fate.
After he survives an ambush beside a remote Swedish lake, an American hit man goes to Rome and contacts his control, Pavel, who sends him to an Abruzzian town with the warning, "No friends." He takes one look and goes instead to nearby Castelvecchio where he poses as a photographer and waits for his control to take care of the Swedish problem.
While waiting, his control gives him a job constructing a special weapon for a Belgian assassin, he converses with the town's priest, and he spends the occasional night with Clara, a local prostitute.
After the priest calls him out on his profession and the Swedes get a line on his whereabouts, is it time to get out?
Jack (George Clooney), an assassin, is relaxing in a remote cabin in Sweden with his lover, Ingrid (Irina Björklund).
The two decide to take a walk on the frozen lake nearby.
While walking, Ingrid notices some footprints.
Jack quickly drags her to cover behind a boulder as someone begins shooting at them.
He kills the shooter and then tells Ingrid to return to the cabin and phone the police while he searches the body.
As she rushes past him, he shoots her in the head.
Returning to the cabin, he kills another assassin.
He then flees to Rome where he contacts an associate named Pavel.
Pavel insists that Jack cannot stay in Rome and sends him to a small town in the mountains of Abruzzo.
Jack becomes nervous, and, disposing of the cell phone which Pavel had given him, flees to another town.
While he is hiding out there, Jack is befriended by an elderly priest, Father Benedetto (Paolo Bonacelli), who pressures him to seek absolution, something which Jack, now going by the name Edward and posing as a photographer, resists.
Jack contacts Pavel, who sets him up with another job.
He meets with a woman, Mathilde (Thekla Reuten), who wants him to build a gun with the firing capacity of a submachine gun and the accuracy of a rifle.
Jack begins work on the weapon as he begins patronizing a prostitute, Clara (Violante Placido).
At the same time, Jack realizes that he is being followed by the same people who tried to kill him in Sweden.
One night, an assassin follows him, but Jack manages to hide.
Just when he is about to shoot the man from behind, a man comes by on a motorscooter, alerting the assassin who fires, missing Jack but killing the motorcyclist.Jack chases the man to a road outside of town and kills him.
After being questioned about the incident by Father Benedetto, Jack meets with Mathilde to test the weapon he has made.
She asks for a few more alterations to it.
While having coffee one day, Jack bumps into Clara and a friend.
Clara invites him on an actual date, and the two begin to deepen their relationship.
But Jack begins to become suspicious of Clara when he finds a gun in her purse and sees her meeting with some men.
He takes her on a picnic where he plans to kill her but cannot bring himself to do it.
Clara explains that she has the gun because of a number of assaults on prostitutes which have occurred in the area, and that the men were cops investigating the case.
After talking to Pavel one last time, Jack agrees to deliver the weapon to Mathilde as his last job.
At the drop off, Jack becomes suspicious that Mathilde plans to kill him when she excuses herself to go to the bathroom.
Before anything can happen, a busload of people arrives, giving Jack cover, and the two go their separate ways.
While driving away, Mathilde is contacted by Pavel, who asks if she has killed Jack.
She informs him no but insists that she is following Jack and will kill him.
Jack meets Clara in the crowd at a local religious festival.
He asks her to go away with him and she joyfully agrees.
Meanwhile, Mathilde is lurking on a nearby rooftop, with Jack in the sights of the weapon he has just delivered to her.However, when she fires at him, the weapon misfires, injuring her fatally; previously, before he delivers the weapon to her, we see him opening the case after a pause, leaving us to assume he booby trapped the gun to misfire.
Jack, hearing the rifle shot, tells Clara to go to the place where they had picnicked and wait for him.
He then chases after Mathilde, followed by Father Benedetto and several alter boys who had been part of the procession.
He find Mathilde dying on the pavement and asks her who she works for.
She dies, and Jack leaves, apologizing to Father Benedetto.
As he leaves he sees Pavel, who had arrived earlier.
The two have a shoot out, and Jack kills Pavel.
As Jack drives to meet Clara, he discovers he is bleeding and realizes he has been wounded.
As he arrives at the picnic spot, Clara smiles with joy, but Jack loses consciousness and crashes into a nearby tree.
