That's one hell of a creepy room. Being all red you can't say for sure if there are any blood stains on the walls, but I bet there are. Doors look ripped out of its frames, like in some deserted mental institution. Anyway, the story goes like in many old-school horror movies where bunch of teenagers are fooling around while investigating some old building when something terribly goes wrong. At some point you realize that your pals are gone and you were left all alone and practically locked inside this horrific facility. Your best bet is to look around and search for some clues and maybe you will find the exit.
If you ever played any of these point and click room escape games, than you probably know that they all come down to solving puzzles and revealing some hidden items which you must than find the purpose of. In this game, eventually it all comes down to collecting three keys, one after another, which you're supposed to use on unlocking certain room doors and eventually to unlock the last door which leads to the outside world. Look down below for a video walkthrough in case you need one.
