Follows the life of 32-year-old Maggie, a well-adjusted radiation technologist, as she tries to discover the true nature of happiness. She knows she cannot look to her two sisters as examples: her older sister, Janet, burdened with three kids, is on tranquilizers, while Lucy, the younger, has always been difficult and discontented. Maggie's love life, however, is blossoming, with three new boyfriends (including a doctor and a lawyer). Meanwhile, Maggie's friend, Rebecca, who designs quizzes for women's magazines, tests Maggie with a quiz that purports to measure expected life span. When they learn, according to the quiz, that Maggie might die in three months unless she discovers true happiness, Maggie takes the light-hearted results seriously and sets off on her quest.
