A young prankster believed by his adoptive parents to be the illegitimate son of Elvis Presley plays "didgibilli" music at an outback truckstop with his friends.

L'il Elvis Jones and the Truckstoppers is an animated adventure comedy about a boy with a talent for trouble and a genius for rock'n'roll. Together with his fellow Truckstoppers, Lionel and Janet, L'il Elvis is the creator of the one and only "didgibilli" sound. L'il Elvis never wanted to be a rock star. He'd rather zoom through the desert on his scoot board, explore some spooky mine or play with his Sea Monkeys. But when you show up on the doorstep of the world's most dedicated Elvis fans, Grace and Len Jones, and you're wrapped in rhinestone swaddling clothes in an old guitar case - you know that fate's taken a hand in your future. And when WC Moore, the world's "nicest billionaire" decides to transform Wannapoo into a 1950's theme town called L'il Memphis and cash in on the didgibilli sound, L'il Elvis and the Truckstoppers find themselves caught in a trap. If they stop playing, the tourists stop coming, the money stops flowing and WC forecloses on everybody's loans.
