Milo and his family go on a family vacation road trip. However, as the Murphys make a pit stop, Milo accidentally boards the RV of another family, the Brulees. Now both families have to meet each other in order for Milo to return to his family, while the Brulees have to cope with Murphy's Law.
The Murphys depart for their family road-trip, and they leave Diogee in the care of Zack and Melissa. After seeing a number of sights and going through a number of mishaps, the family stops at a gas station, only to have Milo accidentally get into the RV of Mr. and Mrs. Brulee and their twin daughters, Charlene and Sharon. After discovering the mix-up, the two families agree to rendezvous, only for both to come across misfortunes along the way due to Murphy's Law. While the Murphys take things in stride and Mr. Brulee's daughters actually enjoy the sights during delays on their way to the Colorado River, Mr. Brulee is greatly distressed.
After numerous mishaps — and incidents in which various Brulee family members are required to put money in jars for various offenses — the RVs of both families end up in the Colorado River. Fortunately, Diogee, who'd escaped the watch of Melissa and Zack as they relaxed, arrives and manages to get both families to safety, though their vehicles are lost in the water. Through all this, the Murphys remain calm, and the Brulees gain a new appreciation for more unique vacations.
