Skittles TV Spot, 'FOX: Bite Size Horror'

In this Bite Size Horror short by Skittles, things get strange during a girl's elevator ride after work. While waiting to go down, the elevator unexpectedly goes up and down until it opens up to a man facing his back towards her. He weakly asks for her help while trying not to reveal himself. As she tries to help him, he mirrors her movements until he asks her to turn around runs into the elevator, leaving her alone in the darkness. Once the elevator opens up showing the next passenger, she's left asking for help as the story repeats itself.
