Minesweeper (film)

Minesweeper is a 1943 American film directed by William A. Berke, a fictional account of a former navy deserter who returns to duty under an assumed name as a sailor aboard a minesweeper, after the attack on Pearl Harbor. The minesweeper used during filming was YMS 121.

Complicating matters, Houston falls into a love triangle, competing with Seaman Elliot Nash Russel Hayden for the affections of Mary Smith Jean Parker, niece of Chief Petty Officer Fixit Smith Guinn Big Boy Williams, who has taken a liking to Houston. Later, Houston overstays his shore leave while gambling, and Smith, having taken over his position, is killed by a mine. Houston nearly deserts again, but instead returns to his ship to take on one last heroic mission.
