Anna needs a time-out from all her boys, and Sam's hunting for a good one to love.  So together they make a getaway to Las Casitas, Mexico, the super luxury spa where Angelenos go to get more sun.  They spend the week waterskiing, scuba diving, saloning, and yes, smooching with boys.  Then a crazy lunch lands them in a deserted mansion, and suddenly their vacation switches from an indie road trip movie to a search-and-rescue blockbuster!
