An international gang steals a piece of diamond called (the Eye of Life) from Paris and transports it to Cairo. The gang works to hide the precious gem inside a store that sells children’s toys, and in a specific game. Mona comes to the toy store to buy a toy for her little brother. He admires one of the toys and, by pure coincidence, finds a hidden diamond inside it.
