Maggie is a student from New York in Paris on exchange for the summer. She's outgoing, cool and adventurous.
Maggie meets and befriends Brenda Walsh and Donna Martin in France and seems relieved to meet other American students who are a bit less über-American than the girls she'd met so far, Texans Ann and Lynnette. They all later attend a French party as a sort of welcoming event for the girls to experience French culture.
Maggie was seen to be speaking perfect French with Brenda, which alienated and frustrated Donna during their stay. Maggie and Brenda seemed to bond stronger than Donna, but Maggie felt that Donna's foray into modeling with Pierre involved ulterior motives, as she had modeled in New York herself and felt the business was corrupted. She was later proven correct in her assumption.
Maggie was later seen talking to Brenda and Donna about Brenda's facade as a French girl with Rick. She later hit on Rick before Brenda informed her of their plans.
