April 1940, Norway. German occupation brings fear, repression, and division. While many turn to resistance, others choose collaboration. Among them emerges the Rinnan Gang — one of the most feared groups in occupied Norway.

Formed in 1942 and working under the German Security Service (SD), the group led by Henry Rinnan specialized in infiltration and betrayal. Posing as resistance members, they gained trust, exposed networks, and sent their victims to arrest, imprisonment, or death.

Operating from Trondheim, they carried out brutal interrogations and helped dismantle resistance across central Norway. By the end of the war, hundreds had been tortured and dozens killed.

After 1945, surviving members were arrested, and trials revealed the full scale of their crimes. Many were sentenced to death and executed.

This is a story of betrayal, terror, and justice.
