Plot
In the 1942 Pacific theatre of World War II, Lieutenant Junior Grade Sam Lawson, USN, is a Japanese-language interpreter who — so far — has avoided combat. His commanding officer, Captain John G. Nolan, unexpectedly cancels his leave and informs Lawson that he is to be assigned to a British infantry commando unit in the New Hebrides Islands for a combat mission.
The British base is in the middle of a large open field, several hundred yards from the edge of the jungle; on the other side of the jungle is a Japanese observation and communications post. Shortly after Lawson's arrival at the base, a patrol of British soldiers sprint out of the jungle and across the open field, pursued by the Japanese. The base commander, Col. Thompson, instructs his men to keep well back, out of enemy range; they watch as the patrol are cut down by Japanese rifle fire.
Lawson's commando group is instructed to destroy the Japanese radio transmitter to prevent them from sounding the alarm about an American naval convoy which is scheduled to appear on the horizon in three days. The post's radio operator transmits an "all's well" signal every night at midnight; it will be Lawson's job to transmit a fake signal (in Japanese) to buy the Allies another 24 hours.
