We are in 1952 and the east coast of New England is being hit by one of the worst storms we can remember. Nobody remembers anything like it and the truth is that the storm is having unforeseeable consequences.
Among them is an accident of a huge oil tanker, which is damaged off the coast. With the storm, its thirty crew are in danger of going to the bottom of the sea with the ship, if someone does not remedy.
Fortunately for the sailors, there are four coast guards in the area who do not think twice and go to sea on board a small boat. They have little chance not to rescue the sailors, but to leave alive themselves.
Despite this, they are thrown into the icy waters in the middle of the storm, since as Coast Guard they are, their mission is to help those who are in trouble, whatever the climatic situation.
