In the Haunted House

For Halloween this year, you and a group of friends decided to go check out the local haunted house. You and your friends waited patiently in the long line, paid for your tickets, and then slowly walked up the creaky steps to the front door. All of a sudden a trapdoor opens and you and your friends are dropped onto a chute that takes all of you to the basement. After checking on everyone you look around and notice that there are four locks on the one and only door in the basement with a note that says "in order to escape, you must not be late, you have four clues to unravel before you will have safe travels." You hear a sound, you turn around, and there on the wall is a clock that started counting down. You have 44 minutes left... You waste no more time and begin looking for clues that will help you and your friends escape this room.
