A tale of betrayal

Burns

I can feel my heart racing; i felt as if my heart was about to  burst out of my chest! I felt the scolding heat of the flames as i wedge my hand then arm into the first hole of the room. My face scrunches as the heat reaches my arm; i shed a tear but after second my tear evaporates! I reach to the back of the hole but nothing, i pull my arm out to see burns all up my arm! I have four more holes to try; i can't do this any more!

 Take a breathe Zoe... you can do this; Sam is crazy but you are going to win Zoe not him! I am a winner Zoe; you can fight this battle because you will WIN! I can do this! He can't destroy me; i am to strong for him to tear apart! Zoe you are strong; no one can tear you down you have been to hell to defeat that knife it's time to be strong, brave and smart! Use your head Zoe you can do this!

I head to the second hole staring at it as if i am stalking my prey. Without hesitation i throw my arm into the hole and reach around the surprisingly deep hole. That's when my confidence disappears; my arm is numb to the point i can't feel it. I had realised the key wasn't in there so i pull my arm out to see the skin pulled apart and dark-red blood ooze out of the wounds. But, i have no choice wither i continue or not because i have to survive this or die trying! 

I reach into the third hole but now it's not the burns i am worrying about... it's the fumes i feel my lungs fill with the toxic air. My lungs are failing to the point where when i cough a small amount of blood comes with it; then i feel a sharp piece of cold metal. The key! I grab it as quick as i can and run the fastest i have ever run before towards the door; i fumble with the key and at first i drop it. Then, i turn the key in the hole and slam the door open; i shut the door to trap the devilish fumes inside that hell.

This is the point i realise i am in a corridor; where am i?
