Trondheim, 1940. Henry Rinnan transforms from a humiliated driver into the Gestapo's secret agent, "Lola." Following the success of the Ålesund operation, he gains recognition, greater power, and his own intelligence unit. Meanwhile, resistance leader Odd Sørli is presented with a unique opportunity to stop him.

An assassination attempt triggers Rinnan's paranoia. When the Gestapo rebuffs him, the Rinnan gang begins interrogating suspects on their own. Resistance member Solveig believes that Rinnan is the resistance hero Bjarne Asp. Meanwhile, Odd is tasked with bringing Rinnan to Sweden alive, a more dangerous mission than killing him.

The fear of losing his grip drives Rinnan to brutality in his hunt for weapons and resistance members. He manipulates Solveig into the "Bandeklosteret" (the gang's headquarters), while the Rinnan gang seeks to get rid of him before the capitulation. When Rinnan's madness strikes Edel, Odd's moral compass collapses, and the hunt for Rinnan becomes personal.
