“In the Coast Guard they say you gotta go out. They don’t say you gotta come back in.” It was a big nor’easter storm off the coast of Massachusetts. It was February 1952, so communications technology was limited. And not one but two tankers split in half. The most experienced Coast Guard crew went off to rescue the first one. When word came in that a second one was sinking, four young men, all under 25 and two who had never been on a rescue operation, took a small boat out into the storm.

That second ship was the Pendleton. Knowing that they had no more than two to three hours before their half of the tanker would sink into the icy storm-tossed waves, they had to decide who would be in charge. “No officers, no rules, every man for himself,” a crew member says. But they realize they must choose between the man who wanted to take the lifeboats or the engineer they did not know as well who said he had a plan (Casey Affleck, understated and compelling). “They may not like you, but they know to listen to you,” one member of the crew admits.

Based on the true story as told in the book by Michael J. Tougias and Casey Sherman, screenwriters Scott Silver, Paul Tamasy and Eric Johnson efficiently introduce us to the characters and the challenges they are facing. Chris Pine plays Bernie Webber, a departure from his usual cocky, confident roles. Bernie is a little shy, but very sincere, and he believes in the rules, not in a rigid way but in a careful way. When we first see him, he is about to see the girl he has been talking to on the phone for the first time and he does not want to get out of the car because he is afraid she will not like him.

And of course she does like him. Her name is Miriam (British actress Holliday Grainger, last seen as an evil stepsister in “Cinderella”). Director Craig Gillespie (of the wonderful “Lars and the Real Girl”) gives them just enough time to get invested in their relationship — and to get us invested in it — before the storm comes in.

Gillespie really gets going when the storm does, though, and those scenes are powerful and exciting. We are in the small boat with Webber as the window shatters and the compass is wiped out. The boat is tossed around like a cork, at one point completely on its side, with monster waves crashing down. And we are in the Pendleton’s engine room as seams burst and beams come down. And then we are back on land, as Miriam tries to find out what is going on, tries to get the commanding officer to bring the rescue team back, and then learns what it is to love a man who risks his life as a part of his job.

In a film like this, the most important job of the director is to make sure we understand how daunting, even impossible, the task is, and then to make sure we get to see what goes into surmounting the obstacles. Some of that is missing here, as when we are told that there are too many men on the Pendleton for the small boat to carry, and then somehow it carries them. The compass is out, there’s no communication, and yet somehow Webber’s crew finds the Pendleton. It may be that no one knows how it worked, but it undercuts the drama to skip over some of those details.

The quiet heroism of these characters is movingly portrayed, and these days, when heroes are hard to come by, this is a touching story of selflessness, courage, and dedication, and exactly the kind of story that Disney tells best.

Parents should know that this story concerns a real-life catastrophic storm with many lives lost. There are scenes of very intense peril, some mild language, and social drinking.

Family discussion: How did the men on the tanker decide who should be in charge? How did Bernie decide when to follow the rules and when not to? What did Miriam learn from her visit to the widow’s house?
