The movie follows the adventure of Tuna, an introverted boy who crosses paths with a group of archaeologists who mysteriously return to their childhood.
A mysterious map and a magical cave unearthed during an excavation in Ephesus brings the adult archaeologists down to the same age as Tuna and his school friend Damla. Tuna's need for these 'new friends' to get rid of Anıl, who bullies him, and the spies' pursuit of the map quickly bring the team closer together. Tuna, Damla and the archaeologists, who are now children, will try to solve the secret of growing up and escape from the agents, while trying to unravel the ancient mystery of Ephesus.
