A copycat killer known as the Trickster sets off bombs in Central City.

Barry Allen was just 11 years old when his mother was killed in a bizarre and terrifying incident and his father was falsely convicted of the murder. With his life changed forever by the tragedy, Barry was taken in and raised by Detective Joe West, the father of Barry’s best friend, Iris. Now, Barry has become a brilliant, driven and endearingly geeky CSI investigator, whose determination to uncover the truth about his mother’s strange death leads him to follow up on every unexplained urban legend and scientific advancement that comes along. Barry’s latest obsession is a cutting-edge particle accelerator, created by visionary physicist Harrison Wells and his S.T.A.R. Labs team members, Caitlin Snow and Cisco Ramon, who claim that this invention will bring about unimaginable advancements in power and medicine. However, something goes horribly wrong during the public unveiling, and when the devastating explosion causes a freak storm, many lives are lost and Barry is struck by lightning. After nine months in a coma, Barry awakens to find his life has changed once again – the accident has given him the power of super speed. Thrilled with his new powers, Barry learns how to control them with the help of Dr. Wells and his team. However, keeping his secret from his best friend Iris is proving to be harder than he thought, especially when Joe’s new partner, Eddie Thawne, catches her eye. When another meta-human attacks the city, it’s time to put Barry’s new powers, and himself, to the test.
