CBS has released the synopsis for the much anticipated crossover event between 'Supergirl' and 'The Flash' entitled World's Finest. The adorably photogenic Melissa Benoist and Grant Gustin share a promotional poster to determine "Who is the fastest person alive?" A rift on the iconic 1967 cover of Superman #199 where Superman raced The Flash to a draw.
The plot of World's Finest pits Kara and Barry against Silver Banshee and Livewire. Here's the official description.
Kara gains a new ally when the lightning-fast superhero The Flash (Grant Gustin) suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home.
“Worlds Finest” airs on CBS March 28th at 8 p.m.
