As an attorney for the stars, 29-year-old Allegra Steinberg is used to hand-holding her celebrity clients through their tangled lives and loves, negotiating major movie deals, and fielding phone calls at all hours of the day and night. But with a career that consumes so much of her time, Allegra has little time for a private life, until a chance encounter with a New York writer turns Allegra's life upside down. And suddenly, she finds herself planning a wedding at her parents' Bel Air home.
As preparations begin for a September ceremony, the chaos of last-minute arrangements, surprise announcements, and ever-increasing anxiety brings out both the best and the worst in everyone. But as couples in each generation of the Steinberg family struggle with broken vows and new hopes, the real meaning of Allegra's wedding emerges. For the bride, the ceremony is a bridge between her past and her future. For her parents, it is a reminder of the bond that holds them all together. And for both families, it is an opportunity for reconciliation, forgiveness, and new hope for the future, as weddings often are for us all.
