Zwei Whisky und ein Sofa (1963)

Beate Dehn and Klaus Hartmann are two ambitious young architects locked in a fierce professional rivalry. When both enter the same high-stakes design competition, their battle of wits turns personal—and seductive. Charming and manipulative, Klaus has a reputation for winning clients with charm, whiskey, and a well-placed sofa, but Beate proves to be a match for his every move.
