Guo Liang
Sam (Bryan Wong) is an ambitious man who stops at nothing to achieve his goals and takes things for granted. A schemer by nature, he has many enemies and was assaulted in a parking lot. He falls into a deep coma and goes to a place called "zero" (零楼) where he is met by "001" (Guo Liang). As Sam's bad deeds and good deeds all cancel out each other, the angels can't decide whether to send him to "basement 1" (hell) or "level 1" (heaven).
