Netflix is going inside the Pentagon with its latest series order.

The streamer has picked up Trinity, a thriller from Bodyguard creator Jed Mercurio and Disneys 20th Television. Gugu Mbatha-Raw and Richard Madden (who starred in Bodyguard) will play the lead roles as a U.S. Navy officer and the secretary of defense.

Mbatha-Raw (Apple TVs Surface and The Morning Show) will play Commander Katherine Decker, the second in command of the USS Kansas, a nuclear submarine. Katherine becomes involved with Secretary of Defense Webb Preston (Madden), then discovers he may be at the heart of a dangerous conspiracy, per the shows logline.

Maddens character is described as having a background in tech, making him different from most politicians, and his drive for innovation is seen as a threat.

Mercurios Bodyguard scored a pair of Emmy nominations (best drama series and best writing for a drama) in 2019. Mercurios credits as a writer and producer also include the BBCs Line of Duty (which streams on Acorn TV in the U.S.) and Bodies and ITVs Trigger Point. He will executive produce Trinity with Jimmy Mulville of Hat Trick Productions and Wendy Mericle. Michael Cuesta (Homeland, Dexter) will direct and executive produce the first two episodes.
