The stakes have been raised in the trailer for the second season of WGN America’s Underground. 

Prison, sedition, the specter of the Civil War — and into it all explodes Moses herself, Harriet Tubman. 

The show focuses on a group of slaves who seek to escape the tyranny of their bondage in Georgia. Things don’t go entirely as they had hoped, and in the new season, they see things go from bad to worse. 

The show stars Aisha Hinds as Tubman, who will be joining series regulars Jurnee Smollett-Bell, Aldis Hodge, Jessica De Gouw and  Alano Miller. The second season is set to feature a new song by executive producer John Legend, with additional music by Raphael Saadiq.

The new season will premiere on WGN America on March 8, 2017.
