Horror of the Fifth Columnist(第五列の恐怖)

A spy (Yukiko Todoroki) infiltrates an aircraft company as an employee and tries to obtain a report on a new engine developed by engineer Morimoto (Ichiro Izawa). Behind it is a spy organization which aims to destroy it. The crew, who fail to rob the report, set a time bomb on the stage at the announcement the secret of the engine as a last resort. Director Hiroyuki Yamamoto is known for national spy movies such as "The Man Who Came from Chongqing" (1943), and worked for Nikkatsu Tamagawa Film Studio before it was integrated into the new company Daiei. This film was long thought to be lost and only recovered in a 70-minute version in the Gosfilm archives in the USSR. Although it was criticized at that time, it is said that a letter of appreciation was also given by the commander of the military police for improving the counterintelligence of the people.
