Both 'Arrow' and 'The Flash' slowed things down a bit this week, but next month will see the two going fast and furious at one another with the arrival of hotly anticipated crossover episodes "Flash vs. Arrow" and "The Brave and the Bold." Find out what brings Barry and Oliver together across two episodes in the first full synopsis from the big 'Arrow'-'Flash' crossover next month!

You're warned of some minor spoilers both for 'The Flash' and 'Arrow,' but it seems The CW has released from its quiver the full synopses of either crossover episode, which begins on December 2 with 'The Flash''s aptly-titled "Flash vs. Arrow," and concludes on December 3's "The Brave and the Bold." In it, we'll see Oliver and co. head to Central City in pursuit of a certain boomerang-wielding killer, as well as what leads to Barry and Oliver trading hyper-fast fisticuffs in the midst of such a lucrative partnership:

The Flash, Tuesday, December 2 – "Flash vs. Arrow"

Barry (Grant Gustin) is thrilled when Oliver (guest star Stephen Amell), Felicity (guest star Emily Bett Rickards) and Diggle (guest star David Ramsey) come to Central City to investigate a case involving a deadly boomerang. Excited about teaming up with his friend, Barry asks Oliver if he’d like to help him stop Ray Bivolo, the meta-human Barry is currently tracking. Bivolo causes people to lose control of their emotions and has been using that skill to rob banks. Unfortunately, the superhero partnership doesn’t go as smoothly as Barry expected. When Oliver tells Barry he still has a lot to learn, Barry sets out to prove him wrong by attempting to stop Bivolo alone. However, when Bivolo infects Barry and sets him on a rage rampage, everyone is in danger, and the only one who can stop him is the Arrow. Meanwhile, Iris (Candice Patton) is furious when Eddie (Rick Cosnett) tries to get a task force to stop The Flash; Joe and Dr. Wells (Tom Cavanagh) agree the Arrow is a bad influence on Barry; and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.

Arrow, Wednesday, December 3 – "The Brave and the Bold"

Oliver (Stephen Amell), Arsenal (Colton Haynes) and Diggle (David Ramsey) track down the location of a boomerang-wielding killer named Digger Harkness (guest star Nick Tarabay) but are surprised when they come face to face with an A.R.G.U.S. team. Diggle asks Lyla (guest star Audrey Marie Anderson) why A.R.G.U.S. is involved but she defers until Harkness attacks the building, killing several agents and targeting Lyla. The Arrow joins the fight and gets help from an old friend—The Flash (guest star Grant Gustin). Harkness manages to get away and Oliver teams up with Barry again to find him before he can get to Lyla. When Harkness plants five bombs in the city that are timed to explode at the same time, both teams must come together to save the city.

Much as we were already on board for Oliver and Barry to throw down, we can't shake the excitement of seeing Grant Gustin play Barry a little more sinister, if only for a taste of what the subsequent 'Flash' hour will bring, suggestively titled "The Man in the Yellow Suit." We've still got 'Arrow''s "Draw Back Your Bow" and at least two more 'Flash' episodes in between, but what do you think? Are you excited to see the first major crossover of either DC drama?
