Handlung
Nichts erscheint dem amerikanischen Physiker Armstrong zu gefährlich, um an eine Formel zu gelangen. Er setzt sich mit seiner Begleiterin in Ost- Berlin ab, wo man ihn für einen willkommenen Überläufer hält. Schon bald macht er den Professor mit der begehrten Formel ausfindig und schreckt vor keinen Mittel zurück, ihrer habhaft zu werden. Der Staatssicherheitsdienst kommt nur allzu schnell hinter Amstrongs wahre Absichten und setzt alles daran, ihn und seine Begleitung aus dem Weg zu räumen.
