某实力雄厚、背景神秘的大集团展开公开招聘,经过激烈角逐,最终有8名精英男女入围最终测试。他们被带入一间近乎全封闭的房间,在测试期间只有三条规则:1)禁止与考官和警卫交谈;2)禁止污损考卷;3)禁止离开房间。违反其中一条规则,将丧失考试的资格。应聘者面前的考卷是白纸一张,却发贸然落笔也是污损考卷的一种。在各种奇怪的规则之下,这几位精英变得手足无措,个性张扬的白人男子(卢克•梅布利 Luke Mably 饰)率先提议应试者们要共同合作,解决问题。拥有不同背景的男女看似走到一起,却不知机关暗藏其中。 与其说是一场激烈的就业测试,毋宁说是一场人性与智慧的大考验……Eight talented candidates have reached the final stage of selection to join the ranks of a mysterious and powerful corporation. Entering a windowless room, an Invigilator gives them eighty minutes to answer one simple question. He outlines three rules they must obey or be disqualified: don't talk to him or the armed guard by the door, don't spoil their papers and don't leave the room. He starts the clock and leaves. The candidates turn over their question papers, only to find they're completely blank. After the initial confusion has subsided, one frustrated candidate writes 'I believe I deserve...,' and is promptly ejected for spoiling. The remaining candidates soon figure out they're permitted to talk to each other, and they agree to cooperate in order to figure out the question: then they can compete to answer it. At first they suspect the question may be hidden in their papers like a security marker in a credit card, and they figure out ways to change their environment to expose the hidden words. But light, liquids and other plans all come to naught. Soon enough, the candidates begin to uncover each other's background, prejudices and hidden agendas. Tensions rise as the clock steadily descends towards zero, and each candidate must decide how far they are willing to go to secure the ultimate job . . .
