What Happens in The Enemy Below: Full Plot Summary

The whole story of The Enemy Below (1957) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

On patrol in the South Atlantic, the American Buckley-class destroyer escort USS Haynes is led by Captain Murrell [Robert Mitchum], a former merchant mariner who has joined the Naval Reserve and is still recovering from injuries after his previous ship was sunk by a German U-boat, leaving him adrift for 21 days. The crew watches him navigate doubt and determination as he assumes command, trying to prove his capability under pressure.

A nearby German U-boat turns the tension into a tense game of cat-and-mouse. The submarine is commanded by Kapitän zur See von Stolberg [Curd Jürgens], a wily World War I veteran who loathes fighting for a Nazi regime he cannot respect. The two captains anticipate each other’s moves, each trying to outguess the other in a high-stakes chess match on the seas.

Murrell subjects von Stolberg’s crew to hourly depth-charge attacks, hoping to force the U-boat to surface where its vulnerabilities are greater. Von Stolberg studies Murrell’s pattern, calculating the rhythm of the American ship’s attacks. He succeeds in torpedoing the Haynes, sending a shock of fear and urgency through the deck. In a calculated ploy to make the damage appear worse than it is, Murrell orders fires lit on the deck, prompting a rapid, controlled abandonment of ship while he keeps a skeletal crew manning the bridge, engine room, and one of the three-inch guns.

When von Stolberg surfaces to finish the Haynes off, Murrell makes a bold, desperate move: he rams the U-boat with Haynes’ bow, riding up over its foredeck and becoming entangled. With his own vessel foundering, von Stolberg orders his crew to set scuttling charges and abandon ship, sealing the danger for everyone aboard the Haynes.

Murrell, the last man aboard, spots von Stolberg on the conning tower and refuses to abandon his mortally wounded executive officer Heinie Schwaffer [Theodore Bikel], who has stood by him since their academy days. Murrell launches a line to the submarine and pulls the pair free, a risky rescue that defies the sinking odds. Lieutenant Ware [David Hedison] returns in the captain’s gig with a mixed party of American and German sailors, racing up cargo nets to pull the final survivors to safety amid the looming explosion of both vessels.

Rescue comes after another U.S. Navy ship arrives, and the German seamen honor Heinie Schwaffer with a burial at sea while Murrell and his crew pay their respects on the Haynes’ stern. In a final, quiet gesture of uneasy friendship, Murrell offers von Stolberg a cigarette as a fragile olive branch. The two captains exchange loaded words that acknowledge their shared losses: von Stolberg confesses, “I should have died a dozen times over, Captain. This time, it was your fault.” Murrell replies, “Fine, next time I won’t throw you the rope.” Von Stolberg answers with a wry smile, “Oh, I think you will.”

The Enemy Below Plot Explained: Your Questions Answered

The questions people ask most about The Enemy Below (1957): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why does Captain Murrell set fires on the Haynes?

Murrell deliberately sets fires on the deck to make the damage from the torpedo appear more severe than it actually is. This is a calculated deception to lure von Stolberg into surfacing for a surface attack, where the U-boat would be more vulnerable to the Haynes' guns. Meanwhile, Murrell maintains a skeleton crew at essential stations while the rest of the crew abandons ship in an orderly manner.

Foreshadowing: Earlier, Murrell subjects the U-boat to hourly depth-charge attacks, trying to force it to surface where it is more exposed.

  • fires
  • deception
  • haynes
  • strategy
  • depth charges
Q2

Why does Murrell ram the U-boat with the Haynes?

When von Stolberg surfaces to deliver the final torpedo strike, Murrell makes a desperate, bold move by ramming the submarine with the Haynes' bow. The ramming traps both vessels together, preventing von Stolberg from escaping or finishing off the damaged American ship. This calculated collision turns what would have been a fatal torpedo attack into a mutual destruction scenario that gives both crews a chance to survive.

Foreshadowing: Murrell had already used deception by setting fires to lure the U-boat to the surface, anticipating this very moment.

  • murrell
  • ram
  • u-boat
  • haynes
  • collision
  • desperate move
Q3

Why does Murrell rescue von Stolberg after ramming his ship?

After the ramming leaves both vessels mortally wounded, Murrell spots von Stolberg on the U-boat's conning tower and chooses to rescue him rather than let him drown. Despite being enemies who just tried to kill each other, Murrell sees von Stolberg as a worthy adversary and a fellow sailor facing death. This act of mercy reflects the mutual respect that has developed between the two captains throughout their battle of wits.

Foreshadowing: Throughout the film, both captains demonstrate understanding and anticipation of each other's tactics, suggesting a deep professional respect.

  • murrell
  • von stolberg
  • rescue
  • respect
  • adversary
  • mercy
Q4

Why does von Stolberg order his crew to abandon ship?

Von Stolberg orders his crew to set scuttling charges and abandon ship because the ramming has left the U-boat severely damaged and interlocked with the Haynes. With his vessel taking on water and facing imminent explosion from the scuttling charges, staying aboard would mean certain death for him and his crew. The ramming has effectively neutralized both vessels, making further resistance impossible.

Foreshadowing: Von Stolberg had studied Murrell's attack patterns carefully and calculated his counter-attacks throughout the engagement.

  • von stolberg
  • abandon
  • scuttling
  • u-boat
  • damage
  • haynes
Q5

What does the cigarette gesture at the end mean?

After the battle ends and Schwaffer is buried at sea, Murrell offers von Stolberg a cigarette on the Haynes' stern. This simple gesture represents a fragile olive branch between former enemies, acknowledging their shared ordeal, mutual respect, and the human connection that exists even between combatants. It symbolizes that despite the violence, they recognize each other as worthy adversaries and fellow sailors.

Foreshadowing: The mutual respect between the two captains has been building throughout their cat-and-mouse duel, each anticipating and admiring the other's tactical decisions.

  • cigarette
  • peace
  • respect
  • murrell
  • von stolberg

Q6

What is Murrell's backstory with the previous ship sinking?

Murrell is a former merchant mariner who joined the Naval Reserve and recently took command of the Haynes. His previous ship was sunk by a German U-boat, leaving him adrift at sea for 21 days before rescue. This traumatic experience has left him still recovering from injuries and facing doubt from his crew about his fitness to command. Taking on the Haynes is his chance to prove himself and overcome the psychological weight of his previous survival.

Foreshadowing: The crew watches Murrell navigate doubt and determination as he assumes command, trying to prove his capability under pressure.

  • 21 days
  • adrift
  • previous ship
  • merchant mariner
Q7

How does von Stolberg survive the depth-charge attacks?

Von Stolberg, a wily World War I veteran, survives Murrell's hourly depth-charge attacks by studying the American captain's patterns and calculating the rhythm of the attacks. He learns to time his movements and positioning to avoid the explosions, demonstrating why he is a formidable opponent. This cat-and-mouse battle is as much a psychological war of wits as it is a physical confrontation.

Foreshadowing: The cat-and-mouse game begins with Murrell trying to predict von Stolberg's movements while von Stolberg does the same.

  • von stolberg
  • depth charges
  • survival
  • pattern
  • world war i veteran

Q8

Who is Heinie Schwaffer and why does Murrell risk his life to save him?

Heinie Schwaffer is Murrell's executive officer who is mortally wounded during the engagement. Murrell refuses to abandon him, even when time is running out before both ships explode. The two have been close since their academy days, giving Murrell a personal reason to risk his own life to pull Schwaffer and von Stolberg to safety with a rescue line. Schwaffer's death is honored with a burial at sea conducted by the German sailors themselves.

Foreshadowing: The summary mentions Schwaffer has stood by Murrell since their academy days, establishing their long friendship.

  • heinie schwaffer
  • executive officer
  • wounded
  • burial at sea
  • academy days
  • murrell
Q9

How does ramming the U-boat save the American crew?

The ramming saves the American crew because it prevents von Stolberg from delivering a second torpedo that would have likely destroyed the Haynes completely. By trapping the two vessels together, Murrell forces von Stolberg into a stalemate, the U-boat cannot finish off the American ship without endangering its own crew. This desperate gambit shifts the dynamic entirely and leads to the mutual abandonment of both vessels.

Foreshadowing: Murrell's decision to set fires on the deck was designed to lure the U-boat into a surface attack, setting up this exact moment.

  • ramming
  • save
  • torpedo
  • haynes
  • u-boat
  • trapped
  • desperate gamble
Q10

What do the captains mean in their final conversation?

In their last exchange, von Stolberg says he should have died and this time it was Murrell's fault, referring to being rescued when he might have preferred a warrior's death. Murrell's reply that he won't throw the rope next time is a half-threat, half-promise that acknowledges their enmity while hinting he would save him again. Von Stolberg's knowing response that Murrell probably will throw the rope captures the uneasy, weary respect that defines their relationship, enemies who have earned each other's admiration.

Foreshadowing: The cigarette gesture earlier established this tone of reluctant respect between the two captains.

  • final exchange
  • von stolberg
  • murrell
  • rope
  • fate
  • respect
  • unresolved
