The title revolves around Harman Smith, a 60-year-old assassin in a wheelchair. He is capable of manifesting seven personalities each with their own deadly abilities, and the whole group is collectively known as the Killer7. The leading personality is revealed to be Garcian Smith, who has the ability, once activated by security cameras or television sets, to call upon the six other members of the Killer7 almost anywhere at any time. Unlike most artistic presentations of multiple personalities, Harman does not just think he is someone else; rather, the personae actually take on their unique physical form and abilities when called upon.
