Fotoula "Toula" Portokalos is her family's black sheep. Her staunchly proud Greek immigrant parents, Gus and Maria, raised their Greek-American kids to follow their cultural traditions of marriage and children. While her older sister followed tradition, Toula is 30 years old, unmarried, and still lives with her parents. Working at Dancing Zorba's, her family's restaurant in Chicago, she longs for an independent life away from the restaurant and her intrusive family, but fears her life will never change. One day at the restaurant, Toula notices a handsome young customer—Ian Miller, a high school teacher. Their romance brings friction and uncertainty to the family as cultures and traditions collide.
