'Supergirl': Legion of Superheroes Synopsis Released

The CW has released the official synopsis for Supergirl's 2018 premiere, titled "Legion of Superheroes."

In the episode, Supergirl is recovering from injuries when Brainiac 5 makes his first appearance in the hopes of helping her.

"I don't want to tease too much," series star Melissa Benoist recently told reporters during a visit to the show's set. "But the fact that the Legion is coming to the show has such a hold in the comic book world, especially with Superman, Martian Manhunter, specifically. That's really exciting for us."

Struggling to heal from her injuries inflicted by Reign (Odette Annable), Supergirl (Melissa Benoist) remains in a dreamlike state, unable to be reached. Mon-El (Chris Wood) recruits one of the Legion members, Brainiac-5 (guest star Jesse Rath), to try to bring her back.

Meanwhile, Reign continues her rampage on the city so the DEO teams up with the Legion of Superheroes to try to stop her. Jesse Warn directed the episode written by Derek Simon & Eric Carrasco.

"Legion of Superheores" will premiere on Monday, January 15 at 8 p.m. ET/PT on The CW.

Disclosure: ComicBook is owned by CBS Interactive, a division of ViacomCBS.
