In New York City, Rosalind Dee (DeCarlo) is a secretary longing to enter high society.

She is rumored of being Carlton Hammond's mistress; he is an older, wealthy man, who dies of a heart attack.

Gambling-club owner Cyril Mace (Kurt Kasznar) joins their table and tries to talk Wade into investing in his Nassau club.

The couple flies to Nassau with Cyril as their guide, tour the island and the club, and meet Rev.

On dock, Cyril is waiting with some newly arrived, rich Americans, who have come to admire her catch; he introduces her to them.

Playboy Doug Duryea (Howard Duff) is there, too, flustering Rosalind, particularly when he asks if they met on Nassau last year.

Back in the club, a tipsy Wade informs Doug that Rosalind is really Linda Darcy.

The couple attend Rand's Sunday, beach-side sermon, which Rosalind finds very inspirational.

Evelyn threatens to tell Doug, but Rosalind says it won't matter; he'll choose her.

Rosalind tells him that Charmaine was upset that about the rumors that she was Carlton's mistress; she took the Hammond's money as she thinks they owed it to her.

He is uncertain over who to believe, but when she refuses to confirm or deny her story, he decides that Rosalind was Carlton's mistress after all.

Cyril then offers Rosalind a deal where she seduces men, takes their money, and they all profit; she laughs at him.

His partners kill him and kidnap Rosalind, heading to their boat and running into Rand on the beach.

Alerted by the flare, the Coast Guard rushes after their boat and fires on it; Rand sabotages their engine to slow it down.

Rosalind and Rand sneak overboard while the partners' boat explodes from shots fired by the Coast Guard.

The film was based on an unpublished novel by Adele Comandini called Rebel Island.

Republic Pictures bought it in January 1954 and assigned Bruce Manning to write the script and Edward Ludwig to direct and produce.

[4] In January 1955, Yvonne De Carlo, who appeared in Magic Fire, signed to play the lead.
