It was sunny beautiful day and Joe was going home from his job. Day was late and he was late so he started to walk a bit faster. Suddenly he notices something strange in the air. Some glittering light hovering few meters away from him. He started to walk towards it to check what it is. He was almost there when he tripped over the stone and fell. Air flashed and now he was sitting in some strange place. The air was different. And sounds were different. All of sudden his clothing started to change. It turned into ragged prehistoric cloth. Joe realised that the glittering light was actually a portal and now he is in prehistoric times. Now he needs to find a way back home, and he need to do it fast to make it in time for a dinner. Cause Joe was hungry. And now Joe was also very angry.
