The Flash is a television show on the CW network. The show focuses on the the life of Central City Police’s forensic scientist, Barry Allen. After being struck by a lightning bolt during a particle accelerator explosion, Barry discovers he has the ability to move at superhuman speeds. Assisted by S.T.A.R. Lab scientists, Harrison Wells, Caitlin Snow and Cisco Ramon (the same scientists responsible for building the faulty particle accelerator), Barry learns to harness his speed. However, Barry was not the only one affected during the particle accelerator explosion. Other humans, in the explosion, were granted “meta-human” abilities. Barry vows to protect Central City from these meta-humans, and other threats as well, as his alter ego- the Flash.
