在红十月核潜艇展开的演习中，艇长雷米斯命令潜艇悄悄改变方向，企图通过这样的方式去窃取到美军的一些情报。当美军的潜艇发现他们无法追踪到苏联潜艇的踪迹时，美军的军官感到十分的惊恐，并且怒斥苏联这种行为是偷袭。于是他们准备要炸毁苏联的红十月核潜艇。然而美国中央情报局的黎博士认为红十月核潜艇的雷米斯极有可能会驾驶潜艇投奔美军。于是中央情报局声称直给博士三天时间，让他必须联系上雷米斯，确认事情的真相，否则就要展开轰炸。

In October 1984, the Cold War between the United States and the Soviet Union entered its peak. The atmosphere between the two sides is always tense, and swords are on the verge of breaking out. At this time, the Soviet Union developed a brand new nuclear submarine, the Red October, and the U.S. Intelligence Agency also learned of the news through its own channels

During the exercise conducted by the Red October nuclear submarine, the captain Remis ordered the submarine to change its direction quietly in an attempt to Steal some intelligence from the US military. When the U.S. submarines discovered that they could not track the Soviet submarine, the U.S. military officers were terrified and angrily denounced the Soviet Union as a sneak attack. So they were going to blow up the Soviet Red October nuclear submarine. However, Dr. Li of the US Central Intelligence Agency believes that Remis of the Red October nuclear submarine is very likely to drive the submarine to defect to the US military. So the CIA claimed to give the doctor three days to contact Remis to confirm the truth of the matter, otherwise the bombing would begin.
