The first story follows a a boy (Jake Logan) and his dog (Murray) whose friendship is threatened by Jake's popular new girlfriend Julianne (Stefanie Scott). The second follows best friends Avalon (Bella Thorne) and Halley (Zendaya Coleman) who are given a chance to turn their web magazine into a real publication at the price of dumping one or the other. The third follows Savannah and Emma (both Mary Mouser) in a modern re-telling of The Prince and the Pauper.
