As we aim closer and closer to the first season finale, The CW's 'Arrow' will take us further into the past we've ever been with this Wednesday's all-new episode "The Undertaking." Yet even as we visit a time before the Queen yacht accident, Oliver will still have plenty to do in modern day, sending Felicity (Emily Bett Rickards) into the field for a dangerous operation. Will Oliver be able to rescue her if things go south, however? Check out an action-packed preview from this Wednesday's 'Arrow' to find out!

It only took 20-something episodes, but at long last The CW's 'Arrow' will finally reveal the meaning of "The Undertaking" this Wednesday. Much of the episode will be told in flashback, but the Oliver Queen of the present still has a dangerous mission to undertake in his own right, rescuing Felicity from a field operation gone haywire.

The Hollywood Reporter managed to snag a first look at the action-packed chaos of "The Undertaking," which series star Stephen Amell promised over Twitter was "Not the biggest action sequence in Ep 21." Oliver brazenly claims during the clip that he never misses, but we're pretty sure we've seen him miss plenty of times before. No fun allowed.
