The Rogues break into Iron Heights, where they've heard that those former Rogues who have returned as Black Lanterns have been busy. Captain Cold is determined to put them down. But Owen Mercer has plans for his father. Barry has been recruited into the Blue Lantern Corps on a temporary basis. Drawn to the intense hope that drives him, the Blue Ring calls out to him that all will be well.
