“Bizaardvark” follows teen comedy bloggers and best friends Paige and Frankie to the sunny shores of Malibu, California, where they have been selected to stay at Vuuugle’s prestigious beach house for the entire summer, along with several other Vuuugle influencers. The comedy duo’s housemates include fellow v-logging star Amelia; their buddy Bernie who lands a room thanks to his grandmother serving as the adult chaperone; and rambunctious tween bloggers Zane (of “Zane Unboxed”) and Rodney (of “What's in M'Hair?”) who run their online channels with their moms. In this ultra-cool oceanview environment, Paige and Frankie – along with their friends – embark on an endless summer of creativity and fun.
