Old friends Lauren Fontaine, Winnie Barnes and Bobby Lazzarini (all Americans) are reunited with Christian Mueller (German) and Ashley Elliot (English) as a new school year begins for them at the American School in Paris, France. All of the students are away from their parents except Ashley, whose father is headmaster at the school. They all live together in a suite for six, with the girls' room on one side, the boys' on the other and a large common room in between. This year there is a new roommate, Jackson Green, another American. At first Jackson does not fit in well at the Academy or with his new suitemates and he wants to leave the school. But he finds a couple of causes worth fighting for: getting rid of school uniforms and making Lauren his girlfriend.

Mr. Eliot is on a cleanliness kick, demanding all students clean up their rooms. Winnie's father, meanwhile, sends her a credit card. The shopaholic Winnie quickly runs up a huge bill, so Jackson comes up with a solution to help her pay it off: start a cleaning service for hire to other students. But when the boys clean Ms. Dupre's apartment, they come upon her next French test, complete with the answers.

Christian is in danger of failing Ms. Dupre's history class. He must get at least a ""B"" on the next test or he will kicked off the basketball team. The guys convince Winnie to tutor Christian and to her great surprise, she finds that she's attracted to him. Also, Lazz does such a good job of cutting Ashley's hair that he and Jackson start their own hair-styling business. But business starts to go sour after they accidentally turn Lauren's hair green!

Winnie's long-absent boyfriend Giuseppe has come back to town. Trouble is, Winnie has neglected to tell him about her new boyfriend Christian. She tries to keep the ex- and current boyfriends in the dark about each other, a plan that is doomed to failure. Also, Lazz and Jackson set up a satellite dish which Mr. Elliot is adamant about having removed--that is, until Ms. Dupre expresses interest in seeing a particular program.

Ursula, a new female student from Germany, arrives at the Academy and asks Christian to show her around. This arouses Winnie's jealousy, and for good reason--Ursula has designs on Christian. Also, a thief has broken into the dorm and Lazzarini has devised a security system to catch him.

Bobby Lazzarini has been dumped by yet another girlfriend, and his teacher Ms. Dupre offers him her sympathies. But Lazz misinterprets the actions of Ms. Dupre, who is his real heartthrob, and concludes that she's in love with him! Also, Jackson has an important audition before an agent, and he recruits Ashley and Winnie as back-up singers. Unfortunately, Lauren wants to make it a trio. Her terrible singing threatens Jackson's chances for success, but no one knows how to tell her the awful truth without seriously hurting her feelings.
