Angela Hamilton, a television game show contestant and a highly skilled physical therapist, has broken up with her fiancée and lost the lease on the building housing her clinic. Although she’s given up on love, she hasn’t given up her dream of building a new therapy clinic, and she turns down an offer by an obviously wealthy older woman to manage a new clinic and instead becomes a contestant in a television game show.

When she enters the game show Charades, all the contestants are masked. During the final round of the show, a strange little makeup artist presents her with a beautiful jeweled mask and cautions her about a future he suggests may offer both love and danger. Before the final round of the game, Jeremy Pryce, the show’s sponsor, arrives on the set where it is obvious to all that in spite of the mask, he is attracted to Angela.

Now, although Angela wins the final round and 50,000 dollars, she knows it’s not enough money to build her dream clinic. Given a choice, she agrees to gamble the 50,000 for a million dollars by masquerading as a famous international play girl, on a Caribbean cruise for 10 days, without being identified. What she doesn’t know is that at least one female celebrity passenger, and possibly more, has been murdered on a Pryce Cruise line ship. She also doesn’t know that Jeremy Pryce will be on board the Queen of Charades in an attempt to identify the killer before he can kill another celebrity.
