You are in a office room. Walk straightly and exit the room. Now walk towards the open room in front of you. Turn left and walk straightly in the passage till you find an open room on your left side. Turn left and enter the room. Now you are in a empty room. Turn around and you are facing a closed wooden door. Slightly turn right and move straightly in the passage till you find an open room on your left side. Turn left and walk towards the white desk in the room. That will be the end point.
