Alone among assassins, Jack is a master craftsman. When a job in Sweden ends more harshly than expected for this American abroad, he vows to his contact Pavel that his next assignment will be his last. Jack reports to the Italian countryside, where he holes up in a small town and relishes being away from death for a spell. The assignment, as specified by a Belgian woman, Mathilde, is in the offing as a weapon is constructed.
