Herr Flick and von Smallhausen are interrogated by the general for impersonating army officers but released on the orders of Himmler - thanks to Helga. A party of intelligence officers are visiting and the Resistance plan to hi-jack their car,steal their uniforms and that way infiltrate the château to get the airmen out.
