Vacuity (2012)

Shortly after a major disaster aboard the XOEH (zoh•ee) space station, Alan Brahm awakes to find himself trapped in the airlock/escape pod, with a torn space suit, and the room rapidly decompressing. With his attempts to force the airlock's door open failing and only minutes left, Alan must make the choice of living to see his family again or sacrificing himself to save the lives of his stranded crew.
