The CW has released a rather short official description with spoilers for the January 16 return episode of The Flash.
The winter premiere is called “The Trial of the Flash” and it will be airing right before the series premiere of the newest DC Comics show Black Lightning at 9PM. Here’s the write-up; hopefully we’ll have some pictures soon.
BARRY FIGHTS FOR HIS LIFE — As Barry’s (Grant Gustin) trial for the murder of Clifford DeVoe begins, Iris (Candice Patton) and Joe (Jesse L. Martin) must decide how far they are willing to go to keep Barry out of prison. Philip Chipera directed the episode written by Lauren Certo & Kristen Kim (#410). Original airdate 1/16/2018.
