After witnessing his mother's murder, and his father wrongly accused, Barry Allen is taken in by Detective West and his family. Becoming a forensic scientist, Allen tries to uncover the truth about his mother's murder, which leads him to Harrison Wells' particle accelerator. When the accelerator causes an explosion, Allen is struck by lightning, and enters a coma. When he wakes up, he learns he has the ability to move at superhuman speeds, though he is not the only meta-human created in the wake of the explosion.
Based on one of the most popular characters from DC Comics, the TV adaptation of “The Flash” was developed by Greg Berlanti, Andrew Kreisberg, and Geoff Johns. The series that airs on The CW Network has three seasons to date with a fourth season underway.
Leading the cast is actor Grant Gustin as Barry Allen, the Flash. He is joined Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Candice Patton, and Jesse Martin as main cast members since the beginning of the show. Actor Keiynan Lonsdale became part of the main cast in season 2.
As he discovers how to use and enhance his abilities, he is joined by bioengineering expert Caitlin, played by Panabaker and mechanical engineer Cisco, played by Valdes. Actor Tom Cavanagh has played different characters in all three seasons, but all of which became sort of a father figure and mentor to Barry.
Aside from exploring Barry’s past, the first season ended with the introduction of the multiverse, which the second season explored deeply. At the end of the second season, Barry’s father, played by actor John Wesley Shipp, was killed by Flash’s enemy in front of him and extreme mourning led him to run back in time in the season finale. The third season started with “Flashpoint,” which is a very popular story arc in the comic series. At the end of the season Barry decides to offer himself to the speed force as consequence to his rash decisions to alter time.
The upcoming fourth season is expected to start without Barry. In his absence, Lonsdale’s Kid Flash is expected play the hero of Central City. The Flash is expected to return for season 4 on October 10, 2017.
