Mia is a bad girl in Miami.

Because of her problems, she is unable to go to a music festival on a Caribbean island that she was looking forward to.

However, she gets a chance to accompany the festival officials as their bodyguard.

The bodyguard is Juri, a high school girl from Tokyo.

Juri likes Mia's looks very much, but Mia doesn't like Juli because of her looks.

Mia & Juri arrive at the festival island in a chartered seaplane, but are almost kidnapped by someone.

It's a completely different island, a smuggling stopover for the South American Mafia.

Mafia's goal is to kidnap Juri for a ransom of $10 million.

Meanwhile, the Miami-Dade Police Department suspects Mia of being the kidnapper.

Will Mia and Juli be able to escape the mafia, get off the island, clear their suspicions, and make it to the music festival?
