Joining them on the trip are Michael's creepy younger siblings, Elvis and Olivia; his overbearing mother, Mary, and her pet Chihuahua, Lucky; his backwoods aunt, Margie; and the cremated remains of his grandmother, June, whose dying wish was to have her ashes scattered in the Grand Canyon. Can the O'Briens pull together to defeat the possessed station wagon...
