Written during the "Red Scare" years, this cross between a documentary and spy thriller focuses on the FBI and their tactics used to follow and track down a group of spies who endanger the sovereignty of the United States. The unspoken message that "anyone can be a spy" delivered by the movie was probably inciteful to say the least during an era of paranoia and fear. Realistic depiction of capabilities and characters however add an atmosphere of realism and believeability to the film.
