Admiral MacPherson sends Otto and Leni to Germany incognito to find and retrieve by a girl named "Angelika". They arrive safely besides the fact that Otto's parachute was stuck in a tree.
Surrender! Give us the girl and have a quick death!
Hurry Otto! Faster!
Otto and Leni go to church on Fraunensil to persuade Angelika to come with them. They take her through a window by lowering some rope. They run away from the church and escape to the main parts of Germany. To get to the rendezvous point with Admiral MacPherson.
Otto's father had been killed by the gestapo several years earlier. While Otto was visiting their former home, they encounter a member of the gestapo. Desperate for vengeance, he engages in a fight with the gestapo. During this fight, Leni sneaks up behind the officer and knocks him out with a beer bottle.
Angelika is dead...... She died saving me.
Oh well, that can't be helped. You did your best.
Hitler's deputy —Reinhard Heydrich— pursues Otto and Leni through snowy mountains to take back Angelika. He shoots at them and manages to take down their plane. Fortunately, Otto, Leni, and Angelika doesn't suffer any serious wounds.

As Otto and Angelika trade places, Angelika starts running to Heydrich with a cartridge of grenades in her jacket. As the bridge they were on explodes in a blazing inferno, Otto and Leni managed to escape. Safe, but with tears streaming down their faces.

As they report to him and talk for a bit, it is revealed that MacPherson was going to use her as a hostage against the Nazis to prevent the war from engaging any further. It is then revealed she is the daughter of someone very important in the Nazi line of power..........
