The Flash: Arrow Crossover International Promo Released

A new international promo for next week's crossover episode of The Flash, "Legends of Today," has been released online.

The clip shows the Flash (Grant Gustin) bickering with Green Arrow (Stephen Amell) while battle Vandal Savage (Casper Crump).

Check it out below.

In its second major crossover event with "Arrow," Vandal Savage (guest star Casper Crump) arrives in Central City and sets his sights on Kendra Saunders (guest star Ciara Renée). After Vandal attacks Kendra and Cisco (Carlos Valdes), they turn to Barry (Grant Gustin) for help. Realizing how dangerous Vandal is, Barry takes Kendra to Star City and asks Oliver and team to hide her until he can figure out how to stop Vandal. However, things quickly go from bad to worse when a man with wings AKA Hawkman (guest star Falk Hentschel) shows up and flies off with Kendra. Meanwhile, Harrison (Tom Cavanagh) develops a serum to make Barry run faster and asks Jay (guest star Teddy Sears) to test it out.

The Flash airs Tuesdays at 8 p.m. ET on The CW.
