After Hours (itch) (Red Wings)

You're an intern in a office with very strict rules. After closing time, no one can be in there. But you, poor tired thing, fell asleep in the middle of a task and, when you woke up, you found yourself alone and locked in the office - after hours! 

So, you have to escape! Good news: you know there is an extra key to the exit door... somewhere. Bad news: the security lights system is on, and if one of those freaking purple lights catches you... you're busted. 

Good luck!
