Four luscious young girls from widely varied backgrounds meet en-route to Miami Beach where each has come for a much needed vacation. Through a series of short sketches the reason behind each girl's decision to suddenly visit the glamorous resort is dramatically played out.
Naive Ann (Linda Hall), molested by her drunken stepfather, seizes the opportunity to escape the squalor of her tenant farm home when she receives an unexpected windfall of money from a deceased uncle. Aided by her work-worn mother who realizes that her beautiful daughter will ruin her life if she remains on the farm, she purchases an airline ticket to Miami Beach.
Blonde and curvaceous Betty (Stella Palma), private secretary to a woman-hungry executive, finally decides that life has more to offer and in a moment of anger resigns her job. Undecided what she should do next, she suddenly makes up her mind to visit Miami Beach before tackling the search for another position.
Kathy (Christy Foushee), a svelte and sophisticated nightclub singer, is
being pressured into marriage by an ardent suitor. Unsure of her real feelings for the man, she decides to take a short vacation in order to work things out in her mind.
A truck-stop diner on a main highway is the background for Dixie (Yanka Mann), whose every day work as a gum chewing, smart talking, sexy waitress brings her into contact with a truck driver who is seeking a safe place to hide a package of money received for transporting stolen diamonds. Agreeing to hide the money only seconds before, Dixie stands by horrified as her friend is brutally gunned down when he leaves the diner. Panic stricken, she packs her clothes, takes the package of money, and begins driving south in her car.
Ann, Betty & Kathy meet on the plane to Miami and as their friendship deepens, decide to room together in the resort city. The new friends check into a plushly luxurious hotel where coincidentally Dixie is also planning to stay. Farm girl Ann, whose vacation wardrobe leaves much to be desired, is introduced to the seductive charms of a bikini by her three new friends and the quartet decide to try out the hotel's inviting pool.
Poolside, the attractive girls are quickly approached by four unattached young men, Frank (Bruce Brown), George (Bob Lee), Harry (Harry Hocker), and Ed (Fred Kost). Before long the four couples make plans to spend the evening together, and a decision is made to visit Miami Beach's famed night spot, the Place Pigalle.
At the club the rapt audience watches the pulse quickening exotic dance interpretations of feather be-decked Wynona, voluptuous Habibi, and oriental Kismet.
With the new friendships fast developing into exciting love affairs, the boys rent a sleek yacht for a day's outing. Engine trouble develops, and the girls decide to picnic on a nearby deserted island while the boys attempt to repair the stalled motor. While swimming and sunbathing on the sun-swept beach, the girls suddenly spot a rowboat approaching with two rough looking men. The girls, frightened and panicked, attempt to hide in the heavy underbrush. The two crooks beach their boat and are in the act of burying a package in the sand when they are attracted by the sound of breaking twigs and realize that someone is watching them.
A hair raising chase through the tropical jungle ensues, with the crooks shooting wildly at the terrified girls. The sounds of gunfire are heard by the boys on the yacht and they quickly swim to the island, sensing that the girls are in some unknown danger. The two gunmen are pursued and finally overcome by the boys but not until George and one of the crooks fight a brutal bloody battle in the rolling surf at the beach edge.
With the gunmen now completely beaten, the boys set them adrift in the rowboat without any oars. The girls tell them about the buried package and after digging it up it is discovered to contain a fortune in diamonds.
Returning to their yacht, they contact the Coast Guard to pick up the drifting gunmen and inform them of the packet of jewels. Emotionally exhausted from the unexpected horrifying turn that the afternoon has taken, the four couples head back for their hotel and safety to resume their Passion Holiday
