Diabolik takes a shot, without imagining that it is a Ginko trap. The inspector, following the signalman into the stolen jewels, surprises Diabolik and Eva in their shelter. The king of terror, forced to flee, leaves the stolen goods of him. While on the run, Eva gets hurt. Diabolik, mercilessly, abandons her. A furious Eva makes a proposal to Ginko: she will bring Diabolik to him in exchange for a safe conduct for abroad. Ginko, forced by the interior minister, reluctantly accepts the pact, and collaborates with Eva in the capture of Diabolik
