In North Africa, submarine commander Charles Sturm is insanely jealous of
any attentions given his beautiful wife Diana, although she is innocent of
infidelity. His violent rages against Pauline stem from a brain
disorder. Due to his suspicions, he has his first officer Jaeckel
transferred.
After a terrible fight with her husband, Diana
runs into the street at night and mingles with the native crowds. She
meets a stranger who buys her perfume, and they fall in love, unaware of the
other's identity. The next morning, the commander introduces Diana to
his new first officer, Lieutenant Sempter, the man with whom she had spent
the night. The commander immediately suspects the two and confirms his
suspicions when he detects Diana's new perfume on Sempter's handkerchief.
Diana goes to the submarine to warn Sempter of her husband's volatile temper
but Sempter thinks she exaggerates.
After confronting his wife and Sempter, the
commander has the submarine submerge and then sabotages their maneuvers so
the submarine collides with a ship and is knocked to the ocean floor, out of
commission. The commander then sabotages the communications device.
Diana proves to the crew that the commander is insane and Sempter takes
control. He manages to save Diana and the crew by flooding the
submarine and having everyone swim out through the buoy hatch. Sempter
exits after a struggle with the commander who, unable to open a door, drowns
with the submarine.
Later, a court finds Sempter guilty of conduct
unbecoming an officer because of his relations with Diana. Diana waits
for him outside the court and they reaffirm their love for each other. |
