Synopsis

Barry und Iris starten nach den jüngsten Ereignissen und einer kurzen Auszeit wieder in den Alltag. Iris fühlt sich jedoch noch nicht bereit, zur Tagesordnung überzugehen und ihrem Job bei CCCMedia gerecht zu werden. Barry hingegen will sich einer neuen Herausforderung stellen und tritt seine Stelle als CSI-Direktor an – und auch als Flash ist er kurz darauf wieder gefordert, denn ein Meta-Wesen namens Captain Boomerang sorgt in der Stadt für Unruhe.
