Supernatural returns with its mid-season premiere episode this Tuesday, January 20, 2015.

The mid-season finale saw Dean (Jensen Ackles) rapidly losing control over the Mark of Cain, leading him to slaughter a house full of humans, even as a horrified Sam watches his brother's descent into darkness.

The mid-season premiere will find Sam (Jared Padalecki) and Castiel (Misha Collins) racing to find a cure for the Mark before Dean succumbs to its murderous effects entirely.

The first look at the trailer of The Hunter Games, however, shows that they will have plenty of obstacles in their path.

The trailer shows Castiel and Sam discussing Dean's murderous tendencies, with Dean cutting in.

Dean says, "There was a time when I was a hunter, not a stone cold killer," pauses in between and adds, "you can say it, you are not wrong, I crossed the line."

The older Winchester brother looks at the Mark and says, "this thing has to go."

Castiel tries to explain to everyone that "it is more than a physical thing, it will take a very powerful force to remove the effect."

He says that the Mark of Cain dates back to the time of creation, adding that "this may pre-date the lore." But also teased a cure saying, "There may be another way."

The promo also shows Crowley (Mark Sheppard) facing a demon anarchy against him, while the Winchester brothers hold Metatron (Curtis Armstrong) prisoner.

Also, Charlie (Felicia Day) returns from Oz.

The official synopsis for the episode reads as follows:

The Aftermath - After the massacre at the ranch, Dean (Jensen Ackles), Sam (Jared Padalecki) and Castiel (Misha Collins) double their efforts to find a cure for the Mark of Cain but there is nothing in the lore that can help them. Desperate, Castiel comes up with an idea that Sam deems the "single worst idea I've ever heard." Meanwhile, Rowena (guest star Ruth Connell) continues to plot against Crowley (Mark Sheppard), and Castiel tries to mend his relationship with Claire (guest star Kathryn Love Newton) who is plotting revenge against Dean for killing her friend. John Badham directed this episode written by Eugenie Ross-Leming & Brad Buckner.
