Betrayal
ITV1 • Aug 4, 2026A veteran MI5 officer who helped prevent major terrorist plots now faces a changed workplace and evolving threats to national security. Married with two children, he must adapt to new professional values while managing growing pressures at home and in the field.
Betrayal keeps the same slow-burn spy tension as Slow Horses, where workplace friction and personal loyalty get ground down day after day. A seasoned intelligence officer faces family strain and a shifting culture, and the danger feels bureaucratic and intimate, darker and more emotionally domestic than the team’s dry chaos.
