After a long hiatus, Legends of Tomorrow is finally back, with fans hooked on the edge of their seats with the premiere episode's surprising reveal. Fans are eager to know if the next episode will feature an appearance by the Justice League of America.

"The Legends travel to Nazi-occupied Paris, but find themselves surrounded by the Justice Society of America (AKA JSA)," according to Comic Book Movie, "The Legends discover a time aberration that threatens the JSA, but the JSA wants nothing to do with them or their help."

Despite that heroes, the Legends, still try their best and find themselves involved in the JSA's mission, an interception of a mysterious package. Still desperate to prove that he should be part of the team, Nate (Nick Zano), faces difficulty when he shares a secret with his grandfather Commander Steel (Matthew MacCaull). This could complicate things for the rookie.

In other characters, "Ray (Brandon Routh) is so focused on impressing the JSA, he puts himself and Vixen (Maisie Richardson-Sellers) in danger," according to Comic Book. "Meanwhile, Stein (Victor Garber) has stepped in as the leader with Rip (Arthur Darvill) gone. But when decisions aren't being made Sara (Caity Lotz) seems to be the one calling the shots. Dominic Purcell and Franz Drameh also star."

The TV series is based on a DC Comic with the same name, and is produced by Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti (Arrow, The Flash, Supergirl), Marc Guggenheim (Arrow, Eli Stone, Percy Jackson: Sea of Monsters), Andrew Kreisberg (Arrow, The Flash, Eli Stone, Warehouse 13), Phil Klemmer (The Tomorrow People, Chuck), Chris Fedak (Forever, Chuck) and Sarah Schechter (Arrow, The Flash).

Legends of Tomorrow Season 2 Episode 2 entitled "Justice Society of America", will be on air Thursday, October 20 at 8 p.m. ET/PT on The CW.
