You are now in a corridor with a raging fire ahead and the water is filling up behind you. There are four doors you can use to escape, you need to tap on each one to find the one that isn't hot by touching the handle. If it glows red then you need to move on to the next door.
Once you have the door that doesn't have a fire behind it, select the paperclip from your inventory and use it to pick the lock. You need to slide the paperclip into the keyhole and move it about until it goes all the way in. One it has picked the lock you can turn the doorknob and head into the room.
