Next week brings a long-awaited event for superhero fans, as Arrow and the Flash team up in a two-hour event that stretches across both characters' shows on The CW.

It all kicks off on Tuesday, December 2 at 8:00 PM on The Flash and then concludes the following night on Arrow. The story finds Oliver and Barry teaming up to fight Captain Boomerang, but things take a deadly turn when Barry is infected by a metahuman that can affect emotions, triggering a dangerous rage within the Flash.

Here's The CW's official description.

Barry is thrilled when Oliver, Felicity and Diggle 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 is furious when Eddie tries to get a task force to stop the Flash, Joe and Dr. Wells agree the Arrow is a bad influence on Barry, and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.

Oliver is an archer who never misses, but Barry is the fastest man alive. Arrow's going to have to use a lot more than his bow to stop an adversary as powerful as Flash. This is must-see TV.
