They'd met on their first day at school - four little girls who were all very different from each other but who somehow became close friends. Their friendship has now lasted 35 years. As their birthdays all fall in the same week they long ago made a pact to spend each big decade birthday together. So far they'd managed it. Now as their 39th birthday looms, Angel, a famous Hollywood actress, announces that this will be her last birthday. Terrified of aging, she absolutely refuses to turn 40. So Lexi, the mother hen of the group and an artist, invites them to Florida for a week-long celebration of this, their last birthday together. The four come together for the celebration but soon things start to unravel and the week ends disastrously. Lexi is distraught. Can their friendship endure? Only time will tell.
