Colonel Tabajdi is away from the barracks for a week so Karádi takes the boys out for landscaping at the nearby hills. The heat is unbearable, and under the influence of Bazsó they figure out the area where they're digging is of archaeological importance, it could be the tomb of Bogdán, the great leader. Now all they have to do is hide valuable treasures there that they can "accidentally" find the next day. Soon a team of archaeologists appear, all of them young girls.
