The Flash: Season 4 (2018)

Barry Allen lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry's life changed when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark matter lightning storm that struck Barry, bestowing him with super-speed and making him the fastest man alive - The Flash.

But Barry wasn't the only person who was given extraordinary abilities that night. The dark matter also created meta-humans, many of whom have wreaked havoc on the city. New threats also arrived from parallel earths and dimensional breaches, under the direction of evil speedsters Zoom and Savitar.

Last season, Barry Allen aka The Flash (Grant Gustin) used his extraordinary abilities to travel back in time and save his mother's life, and inadvertently created an alternate timeline known as Flashpoint. The phenomenon not only gave birth to the villainous God of Speed known as Savitar, but changed the lives of Caitlin Snow (Danielle Panabaker) and Wally West (Keiynan Lonsdale) forever.

With the help of his adoptive father, Detective Joe West (Jesse L. Martin), his fiancé Iris West (Candice Patton), and his friends at S.T.A.R. Labs - Cisco Ramon (Carlos Valdes) and Harrison Wells (Tom Cavanaugh) -- Barry continues to protect the people of Central City from the meta-humans that threaten it. But first, he'll have to escape the Speed Force - an extra-dimensional entity teeming with unknown dangers - that Barry sacrificed himself to in order to save Central City.

The Flash: Season 4 is released on DVD and Blu-ray 24th September 2018 from Warner Home Video.
