Toula is 30. And unmarried. Which means as a nice Greek girl - she's a failure. All her cousins did the right thing - married Greek boys and made Greek babies. So everyone worries: what will become of Toula? Then one day she sees the ultimate unattainable guy and realizes the only way her life will get better is if he gets away from her big, fat Greek family. Toula escapes from the family restaurant. She exchanges her seating hostess jacket for a college diploma, convinces her aunt to give her a new job, and trades in her coke bottle glasses for contact lenses, just in time for "him" to walk back into her life. Ian Miller is tall, handsome but definitely not Greek. Their courtship is an Olympian culture clash. Can Ian handle Toula, her parents, her aunts, uncles, cousins and several centuries of Greek heritage? Will Toula discover the love she's been missing right in the heart of her big, fat family? One thing is for sure, for better or worse, for richer or poorer, with Ian's proposal Toula is headed for her big, fat Greek wedding.
