Jussie Smollet, better known as Jamal Lyon from Empire, will guest star in forthcoming WGN America drama series, Underground. His real life sister, Jurnee Smollet-Bell is a star on the one-hour drama.

If you thought Underground will be about slaves then you guessed right:

It will follow the story of slaves fighting for their lives, families, future, and freedom. Jussie will play a slaved named Josey with trust issues worst than Drake. His sister will play a shy, but courageous slave named Rosalee.

The series is supposed to premiere next year.
