Andre, backed up by the other Blackhawks, approaches female spy Natasha Zero to gain a deadly nerve gas and prevent it from falling into enemy hands. Natasha leads Andre into a trap set by her buyer, Le Croc. The other Blackhawks appear to fall victim to the nerve gas, but they are protected with the aid of nose filters. The Blackhawks then apprehend Le Croc and Natasha, exposing the female spy as a man.
