Julia and the rest of the family are in charge of catering for a rich woman's Halloween party. The children are supposed to pretend they are not related to Julia though, as the woman doesn't like family businesses. When Andrew and Keith flirt with the woman's beautiful daughters, Julia 'fires' them. But the boys disguise themselves with costumes and sneak into the party anyway--causing some cases of mistaken identity.
