While investigating a crime scene, Barry Allen has visions of Wally West, Eobard Thawne and an individual in white clothes. While running through Central City, Barry encounters Wally, who had been absorbed into the Speed Force and attempts to warn Barry about the involvement of someone in the timeline. Just as Wally is about to be absorbed into the Speed Force, Barry remembers him and pulls him out. Reuniting, Wally also warns Barry that they "are being watched". After discussing what to do next, Barry goes to visit Batman to talk about the button they found.

While at a crime scene, Barry reunites with his old friend August Heart, who was present on the day he was struck by lightning and gained his powers. Soon, citizens all over Central City gain the powers of the Speed Force seemingly at random.

As Barry neglects to train the new Kid Flash (Who coincidentally is also named Wally West), he decides to take matters into his own hands and battle the Shade.

After the supervillain team The Rogues has mysteriously disappeared, Flash goes looking for them. The Rogues enact deadly traps to kill Flash once and for all.

Eobard Thawne (aka the Reverse Flash) returns once again to ruin Barry's life and threatens to strike down everyone close to him.

Barry's new powers aren't working properly as he faces a new villain, Bloodwork, who has secret ties to Barry Allen.
