“Greyhound” (2020) is a World War II naval drama directed by Aaron Schneider and based on the 1955 novel “The Good Shepherd” by C.S. Forester. The film stars Tom Hanks, who also wrote the screenplay.

The story is set in the early days of the United States’ involvement in World War II and follows Captain Ernest Krause (played by Hanks) as he commands the USS Keeling, codenamed “Greyhound.” Krause is an inexperienced naval officer given his first command mission: leading an international convoy of 37 Allied ships across the treacherous North Atlantic, where they must evade and confront deadly German U-boats.

The film takes place over five days in the Battle of the Atlantic, a critical campaign where the Allies strive to maintain control of the vital supply routes between North America and Europe. The convoy enters a perilous stretch known as the “Black Pit,” where they are out of range of air cover and vulnerable to submarine attacks.

Krause faces numerous challenges, including relentless attacks from the German U-boats, dwindling supplies, and his own self-doubt. Despite the intense pressure and constant danger, he demonstrates steadfast leadership and courage. The narrative emphasizes the cat-and-mouse tactics between the convoy and the U-boats, with intense naval combat scenes and a focus on the strategic and emotional toll of warfare.

Throughout the ordeal, Krause remains dedicated to his duty, driven by a sense of responsibility for his men and the mission. His resolve is tested as he contends with the physical and psychological demands of commanding in wartime.

“Greyhound” is noted for its tense and realistic depiction of naval warfare, and Tom Hanks’ performance as a stoic and determined captain. The film’s focus on strategy, the high stakes of the convoy mission, and the harrowing experiences of the crew make it a gripping wartime thriller.
