The Griffin family is about to embark in the journey of a lifetime. After taking two planes to San Francisco, they will take a road trip down the pacific coast exploring the distant land of California, a place which the two children have never before dared to venture. All the while, Thomas will be chronicling the adventure with his trusty (and hopefully waterproof) video camera. Both for them and for their parents, this will surely prove to be a deeply rewarding and cathartic experience.
