Newcomer Thuso Mbedu goes in search of freedom in the atmospheric trailer for The Underground Railroad.

Based on the Pulitzer Prize-winning novel by US author Colson Whitehead, the 10-part series will tell the story of Cora Randall, played by Mbedu, as she flees a Georgia plantation and slavery.

She goes in search of the rumoured Underground Railroad, a network of secret routes and safe houses, but instead finds an actual railroad, manned by engineers and conductors, hidden beneath the southern state.

The two-minute teaser sees Randall pursued by Ridgeway, played by Australian star Joel Edgerton, a bounty hunter fixated on bringing her back to the plantation.

As she travels from state to state, she confronts the legacy of her mother Mabel, who also escaped to freedom and was pursued unsuccessfully by Ridgeway.

Oscar-winning director Barry Jenkins, whose credits include Moonlight and If Beale Street Could Talk, is showrunner and directs all 10 episodes of the limited series.
