The film follows the fun adventures of three ancient Egyptian mummies who live in an underground secret city, hidden in ancient Egypt. The trio includes a princess, a former charioteer, and his younger brother, along with their pet baby crocodile. Through a series of unfortunate events, the mummies end up in present-day London and embark on a wacky and hilarious journey in search of an old ring belonging to the Royal Family, which was stolen by the ambitious archaeologist Lord Carnaby.
