The plot of Heroes is designed to be similar to the stories of comic books with small story arcs built into the series' overall large story arc plot. Each season of Heroes is designed to involve ordinary people who discover extraordinary powers, and how these abilities take effect in the character's lives.
Season one featured 23 episodes, which aired on Mondays at 9:00 pm in the United States, beginning on September 23, 2006. Season one consisted of Volume One, known as Genesis. The series went on hiatus twice; first from December 4, 2006 to January 22, 2007, and again from March 5 to April 23, 2007, with the season finale airing on May 21, 2007. The volume begins as a seemingly ordinary group of people gradually become aware that they have special abilities. Events illustrate their reactions to these powers, and how the discovery affects their personal and professional lives. At the same time, several ordinary individuals are investigating the origins and extent of these abilities. Mohinder Suresh, a geneticist, continues his late father's research into the biological source of the change, while Noah Bennet represents a secret organization known only as "The Company". While coping with these new abilities, each of the characters is drawn, willingly or unwillingly, into the Company's conspiracy to control superpowered people and into a race to stop an explosion from destroying New York City.
