Jennie Lee is the lead singer of the all-girl
Baltimore rock band, the Mystery. At her high school graduation, Jennie gives her valedictorian speech while fellow band member and bass guitarist Daryle accepts a proposal from her high school sweetheart Frankie. Jennie and the band are going to Florida to audition for a gig at a nightclub for the summer. However, many problems arise, first Jennie's older brother doesn't want her to go because it could alter her college plans; second, the band's keyboardist has unexpectedly left the band, and third, their drummer Mooch insulted a gang member who then destroyed their van. She tells the band that she borrowed a van from her friend but with guitarist Billie's help, she stole the gang member's personal van. After recruiting a male keyboard player Nicky, the band heads south for the audition. Arriving at the nightclub after closing, they fear they missed their audition. Not wanting to have to return, the band finds the owner Martin Falcon's home address to make him listen to them play. However, when they arrive at his beach house, they let themselves in and find Falcon is not home. They do find Hamlet, Falcon's pet Doberman Pincher dog, who, after Billy sings him a song, becomes fast friends with them. Falcon arrives, drunk, and assumes they are thieves. Explaining who they are, Jennie pleads that he listen to their music, but Falcon informs them that they are in fact a day early. Having very little money and no place to stay, he offers them the room the winners are supposed to be staying in for the summer. The "room" is a tool shack with room for 5 beds. The next night, the band auditions, and the overwhelming applauding crowd response convinces Falcon to hire them for the summer. The band members stick out like a sore thumb in the preppy beachside area, especially Mooch, who refuses to take off her black leather jacket, although the weather is hot. Daryle (who has broken up with Frankie) starts dating a local rich boy and gets the band invited to his parties. Billy, uncomfortable, starts taking more pills than usual to cope with her depression. Jennie encourages Mooch to spend time with Nicky, who has a crush on her, and Jennie begins seeing the older Falcon. Falcon tells Jennie he has a music agent friend who books bands for European gigs and is coming to the club to watch the band perform. When Falcon learns that she is considering moving in with him, breaks up with her as he doesn't want her to give up any opportunities because of him. Billy nearly overdoses, and Frankie causes a small riot when he goes to the club and sees Daryle on stage being ogled by the locals. On the night the agent goes to the club, Jennie runs out just after performing a song written by Falcon, especially for the band, and the street gang finally catches up with Mooch for taking their van. The band all helps Mooch fight off the leader and, finally, Hamlet the dog chases them from the club, who are then arrested. When asked what the agent said, Jennie implies that the agent loved their music but she turned down his offer for the band to play in European clubs. Upset with Jennie that she would turn down such a huge opportunity, Nicky explains to the rest that the music agent did not want the band, but only Jennie with studio musicians. She decides it wouldn't have been any fun without them. Jennie says goodbye to Falcon, and the band heads home with Hamlet now a part of the band. ==Cast==
