From IMDB:
The Coast Guard makes a daring rescue attempt off the coast of Cape Cod after a pair of oil tankers are destroyed during a blizzard in 1952.
Those of you familiar with Cape Cod in Massachusetts may feel a personal connection with this gripping reenactment of a Coast Guard rescue off Chatham harbor. From the Wikipedia article comes this quote:
The Finest Hours is a 2016 American historical disaster drama–thriller film directed by Craig Gillespie and produced by Walt Disney Pictures. The screenplay, written by Eric Johnson, Scott Silver, and Paul Tamasy, is based on The Finest Hours: The True Story of the U.S. Coast Guard’s Most Daring Sea Rescue by Michael J. Tougias and Casey Sherman. The film stars Chris Pine, Casey Affleck, Ben Foster, Holliday Grainger, John Ortiz, and Eric Bana, and chronicles the true account of the 1952 United States Coast Guard rescue of the SS Pendleton, after it split apart during a nor’easter off the New England coast.[
Do not be put off by the start of the film where Bernie Webber (played by Chris Pines) begins his romance with his wife to be, Miriam (played by Holliday Grainger). Much of the film is involved with this romance.
More than any other theme, the notion of true leadership plays an important part. For the rescue to succeed Bernie Webber risked his life while at times disobeying orders. Equally important was the fact that Ray Sybert (played by Casey Affleck) had to transform himself from a super expert reclusive naval engineer geek into a leader after the tanker split in half.
Try to read the final screen notes, but the Wikipedia article also helps.
Just the harrowing scenes of the rescue in a raging sea make watching this film an exciting adventure.
