Another school year has come to an end and all the girls are preparing or their summer vacation. They each reminisce about the last six years they have spent together (via flashbacks). However, leaving one another on good terms is something that may not happen when an accident causes yet another rift between Jo and Blair. Flashbacks and memories of the past continue as the girls finish getting ready for their summer vacations. However, saying goodbye to one another appears to be easy for all them especially since fights are brewing between Blair and Jo and Natalie and Tootie.
