CBS has released a poster and new plot details for the upcoming Supergirl crossover with CW’s The Flash on March 28th.
In the episode entitled “World’s Finest,” Supergirl joins forces with a lightning-fast—and super dreamy—hero, The Flash (Grant Gustin), to take out two villains. Lost and confused after spiraling from his universe and landing in Kara’s, The Flash asks for her help in finding his way back home.
