McHale's Navy (1962)

S3E8 The British Also Have Ensigns

Title: The British Also Have Ensigns Plot: Binghamton has a hidden agenda when he assigns a rather awkward British Sub-Lieutenant to the 73 Crew. When this clumsy officer mistakenly apprehends Fuji, believing him to be a spy, McHale and Parker devise a daring scheme to rescue their Japanese companion. Their plan becomes even more precarious with the unexpected arrival of the Sub-Lieutenant's Admiral cousin, adding extra tension to their already risky operation.
