It is the Last day before Katie graduates from university, she and six friends went into a soon-to-be demolished residential hall for a puzzle game, "Seven things to do before death". It's believed that if the puzzle is figured out, and the players have completed all of "Seven things", thus one can live a fulfilling life . However, after the first task is completed, one of the student suspiciously dies, and the rest are left feeling perplexed. Coincidently, a foreign student that was declared missing, suddenly shows up out of nowhere, and has self claimed proof that "Seven things to do before death" is an experiment to test the accuracy of Ancient Chinese Astrology, instead of the game they believed it to be. They were deceived, the "Seven things" were never about enriching people's lives, adversely , it could be the reason behind some of their deaths?
