Handsome blond Tab Hunter (as Michael "Mike" Dugan) and desirably beautiful nurse Linda Darnell (as Elizabeth "Lizzie" Smythe) are shipwrecked in the Pacific Ocean during a World War II bombing. They bicker about his being too boyish a "pride of the Marines," and which of the two is top commander. She's a lieutenant. He's a corporal, but pulls rank as the duo's captain. They find a skeleton on "Saturday Island" (known in the US as "Island of Desire") and read the diary of "Grimshaw"
In a flashback to 1930, John Laurie (as Grimshaw) loses native lover Sheila Chong (as Tukua) and is attacked by a sea serpent
Back in the present, Mr. Hunter finds himself increasingly aroused by his island mate, but Ms. Darnell plays very hard to get. She calls herself an "old maid," but still looks mighty attractive. Hunter is a young Adonis. As soon as things heat up for the couple, a plane crash lands British pilot Donald Gray (as William "Bill" Peck) on the island. He loses his left arm to the crash, but his heart to Darnell. This is more interesting as a story about loyalty than it is about sex, but it's too awkwardly played.
