"Squid Game," which premiered in 2021,  follows hundreds of financially challenged people who compete for cash in deadly versions of children's games.

The trailer, released Wednesday on Netflix's YouTube channels and social media pages, opens with protagonist Seong Gi-hun (played by Lee Jung-jae) stepping into a limo. 

Inside the vehicle, the enigmatic Front Man (Lee Byung-hun), who oversees the deadly games, confronts Gi-hun with the question, "What do you want from me?", to which he resolutely responds, "Put me back in the game."

In the Red Light, Green Light game, Gi-hun tries to lead the other contestants to prevent deaths. But some players, including the character portrayed by Choi Seung-hyun, deliberately endanger the others and push them to their demise.

The trailer also features the new cast members, including Yang Dong-geun and Kang Ae-shim as a debt-burdened mother and son, Yim Si-wan and Jo Yu-ri, whose characters seem to share a connection, as well as Park Sung-hoon and Kang Ha-neul.

Wi Ha-jun also returns as Hwang Jun-ho, who appears to lead his fellow police officers in an operation to the island where the clandestine games are taking place.

Towards the end of the nearly two-minute trailer, Gi-heun remarks, "Those who created this game, we should fight them."

The second season of "Squid Game" is scheduled for release on December 26.
