Airing May 16, the episode will reunite The Flash and Captain Cold, aka Leonard Snart, once more to take down the self-proclaimed God of Speed.  You can read the synopsis for "Infantino Street" below.

With only 24 hours left until Savitar murders Iris (Candice Patton), Barry (Grant Gustin) struggles to save the woman he loves and makes the choice to use any means necessary to do so. Realizing he has one option left to save her, The Flash turns to Captain Cold (Wentworth Miller) for help.

The title of the episode is most certainly a nod to Carmine Infantino, co-creator of Barry Allen during the Silver Age of comics. In next week's episode titled “I Know Who You Are," Barry tries to track down Tracy Brand, a scientist that may be the key to stopping Savitar, while a battle between Killer Frost and Vibe is set to go down..
