An Iranian-fronted oil company has secretly funded the Islamic Republican Front, embedding six highly intelligent sleeper agents deep inside the British establishment. Groomed through elite universities and coded with river names, they now hold sensitive positions across MI5, MI6, GCHQ, and key government departments — giving the IRF access to classified intelligence at the highest level.

As Britain faces a surge in illegal Channel crossings, Max-Catt is tasked with covertly disrupting the people-smuggling networks operating from the French coast to Dover. What he uncovers is far more dangerous: a recruitment pipeline where vulnerable migrants are indoctrinated and weaponised in return for food, shelter, and protection, all in service of a long-term plan to destabilise the UK from within.

Surrounded by double agents and betrayal — including one operating alarmingly close inside Bastion itself — Max must expose the network before it can strike. With trust shattered and loyalties blurred, the most dangerous enemy is no longer outside the system… but buried deep inside it.
