When a camping trip unleashes a reluctant Peachey family on the great outdoors, it’s up to their savvy dog, McTavish, to show them how it’s done.

It’s summer, and the Peachey family is in crisis — again. Where will they go for their vacation? Betty Peachey thinks that camping is the answer, and Ma Peachey knows just the place. But Pa Peachey is convinced that terrible dangers lurk in the world of nature, Ollie only wants to know if there are dance clubs, and Ava would rather stay home and read German philosophy. Will rescue dog McTavish figure out how to turn the Peacheys into happy campers — and get them to brave the sparkling river and scenic mountainside before they pack up their tent and go home?
