Sky has released a new trailer for its upcoming limited series The Regime.

The series stars Kate Winslet, Matthias Schoenaerts, Guillaume Gallienne, Andrea Riseborough, Martha Plimpton, and Hugh Grant.

It  tells the story of life within the walls of a modern authoritarian regime as it begins to unravel. After not leaving the palace for quite some time, Chancellor Elena Vernham (Kate Winslet) has grown increasingly paranoid and unstable when she turns to a volatile soldier, Herbert Zubak (Matthias Schoenaerts), as an unlikely confidant.

As Zubak’s influence over the chancellor continues to grow, Elena’s attempts to expand her power eventually result in both the palace and the country fracturing around her. 

All six episodes will debut in April in the UK exclusively on Sky Atlantic and NOW.
