Geeky, perpetually late CSI Barry Allen was struck by a bolt of lightning that was the result of a freak storm caused by a malfunctioning particle accelerator. After a nine-month coma, Barry awoke to find himself endowed with super speed.

Working alongside scientists Cisco Ramon, Caitlin Snow, and Harrison Wells as well as his surrogate father, Detective Joe West, Barry uses his new-found powers to save people and help contain other meta-humans who also gained powers in the explosion as well as to free his father from a false murder conviction.
