Four bright teenage girls from St. George's, an international school in Rome, put their lives on the line when they utilize their school banquet to help save a baby rhinoceros from a bankrupt Italian zoo. Inspired by a local zookeeper's story as an African game warden, the girls set a plan in motion when they discovered the zoo's new director was a poacher and had bad intentions set for the zoo.
Each girl is powerful, and they use their unique talents, ingenuity, and diverse friendship to outsmart the director's evil intentions. The catacombs will awaken as the girls utilize ancient Roman ruins and the city's streets as their battleground, turning the story of St. George upside down to save a baby rhino.
