The House on Carroll Street (1988)

I was surprised to find a well done film noir from the 1980s, but here it is. After losing her job for refusing to name names, Kelly McGillis finds herself witness to a strange conversation involving a United States senator, played by the amazing Mandy Patinkin, and some mysterious Germans. Being drawn into the conspiracy, she eventually enlists the help of an FBI agent played by Jeff Daniels. Set during the early days of the Cold War, it has a very Hitchcockian feel and involves some captivating twists and turns, culminating in a thrilling climax.
