The Flash

When a powerful alien threat arrives on Earth under mysterious circumstances, Barry, Iris and the rest of Team Flash are pushed to their limits in a desperate battle to save the world. Flash will also need to enlist the help of some old friends.

Despero warns The Flash that great tragedies will befall the speedster and cause him to lose his mind. Once that happens, Armageddon will begin. Determined to prove Despero wrong, Barry doubles down on proving his innocence.

After things take a dire turn with Despero, Barry meets Black Lightning at the Hall of Justice. Meanwhile, Iris suspects that something is off with Despero's vision of the future, so she seeks help from a powerful ally.

The exciting conclusion to the five-part Armageddon event presents an opportunity for The Flash to end his lifelong battle with Reverse Flash for good, but the payoff could be too much for Barry and the team to handle. Mia Queen drops in.

Barry trusts his instincts during a murder investigation, believing the suspect, despite the overwhelming evidence against him. Meanwhile, Iris gives Allegra an opportunity to be a mentor.
