Gorilla Grodd is after Central City's Speed Force but the one thing Barry Allen can't outrun is the truth, and his nemesis knows a terrible secret about the Fastest Man Alive. As Barry battles Grodd, he loses what he prizes most in the world and must call in an Wally West to protect Central City while he sets out to get it back. But with a new Flash protecting his city, will Barry be willing to cross lines he never crossed before?"--
