In this new trailer that was unveiled at PaleyFest 2015, "Arrow" finds Oliver Queen (Stephen Amell) and his friends confronted with a day of reckoning.

The trailer, which includes some major spoilers for the rest of season three, warns of Ra's al Ghul's approach, teases the Suicide Squad, shows the return of a dead character and reveals Oliver's true identity to two major players. In sum, it promises to raise the stakes even higher for this season's finale.

"Arrow" returns to the CW on March 18 at 8 p.m. EST.
