The Secret Tunnel!!

The moment the the tile floor lowered, it revealed a staircase leading downstairs. 

"Damn....There's seems to be some secret beneath this house" HK exclaimed while leaning over to look beneath. 

Reaching for her gun, Sia turned on the flashlight. Turning to the two officers who were standing still, she ordered "You both stay here, don't let anyone else come down" then turning to HK she ordered "You follow me. May be your Dog Poop luck might be useful"

"....." 

Sighing helplessly, HK pulled out his gun and followed Sia downstairs, covering her back. 

As they made their way downstairs, what awaited them was not a basement room or anything, instead wall which seemed to be password protected. 

"Damn, this place is exciting me now. I wonder what is behind this that requires so much protection?" HK exclaimed while looking around. 

Not speaking much, Sia observed the Dialpad and suddenly typed in a few numbers.
