About Logan[]
Logan was a Sandman who was ordered by the master computer to infiltrate the Runners and to locate and destroy the Sanctuary they were seeking. Not permitted to inform any other Sandmen who might otherwise have assisted him, the computer told him that he would begin his assignment by becoming a Runner seeking Sanctuary. (The film explained that the underground's activities had caused Deep Sleep, the organization for which the Sandmen worked, to lose one thousand fifty-six Runners. Logan's assignment was according to "Procedure 033-03," and his mission was listed as "Assignment 033-03" when he was interrogated.) It enabled him to do this by altering his Lifeclock to that of a Runner. (In the film, Logan was 26 years old.) Before being so ordered, Logan 5 encountered Jessica 6, whom he later learned belonged to the underground.
When he and Jessica broke the seals of "The City" and managed to make their way outside, locating (in the film) the exposed ruins of a by-then abandoned Washington, D.C., Logan realized that the Sanctuary the Runners were all seeking did not actually exist beyond the hope of inhabitants of the City living past the age of thirty years. (They were required to die at the age of twenty-one in the novel.) Beyond that, he realized, the lifeclocks, "Carrousel(sic)," and the very idea of "renewal" were all a lie; when he and Jessica returned to the City, he did all he could to attempt to convince others of all this. Not till the Deep Sleep master computer's inability to accept the truth of what Logan revealed to it under interrogation caused it to destroy itself was he successful in this.
