Simon Pegg and Hannah Khalique-Brown return for series 2 of the cyber-thriller. 

Channel 4 has announced a second series of The Undeclared War. The new six-part run of the cyber-thriller comes from writer Colin Teevan (Das Boot), with Paul McGuigan (Inside Man) directing.

Series 1 was presaged with a chilling faux-Prime Ministerial broadcast, so look out for something similarly creative this tine.

Here’s what we know about series 2:

Simon Pegg returns as Danny Patrick, Director of Operations at GCHQ (U.K.’s Government Communications Headquarters). Siân Brooke joins the series as Barbara Patrick, Danny’s wife, ex-MI6 and now an analyst at GCHQ.

Set in 2024, The Undeclared War returns with a fresh wave of tension and drama as the elite Malware Department at GCHQ grapples with the aftermath of a devastating Russian cyber-attack. Just when it seems the UK has gained the upper hand, Danny and the team uncover a far more dangerous threat.

Hannah Khalique-Brown returns as Saara Parvin, a brilliant young coder on placement at GCHQ. Alex Jennings returns as Danny’s boss, David Neal, the Director of GCHQ. Danny Sapani (Black Panther) plays Charlie Francis, GCHQ’s Head of Security and Danny’s childhood friend.

Ed Stoppard returns as Richard Marston, the newly elevated Foreign Secretary and a constant thorn in Danny’s side. Chloe Pirrie will play Lt Colonel Roz Cavendish, seconded by Marston to GCHQ in the newly created role of Director of Rapid Response, a move which Danny interprets as a threat to his authority.

The show comes from producers Playground (Wolf Hall), Stonehenge Films and Universal International Studios, a division of Universal Studio Group.

We’ll keep you posted.
