Flash - Season 1 of this action-adventure series follows Barry Allen (Grant Gustin), an assistant police forensic investigator who was orphaned when his father was falsely imprisoned following the mysterious murder of his mother. The season begins with Allen being struck by lightning during an intense storm caused by a particle accelerator explosion that bathes the city with an unusual form of radiation. The strike puts Allen in a coma for nine months. When he wakes up, he quickly learns he can move at superhuman speeds. It's a fate that also befalls others in the wake of the explosion and storm, creating several "metahumans." Allen then uses his newfound power to fight crime and go on a hunt for his mother's true killer. Candace Patton, Danielle Panabaker, Rick Cosnett, Carlos Valdes, Tom Cavanagh and Jesse L. Martin also star.
