　　Jack Willis is a handsome roadtrain driver with a secret - he has just become a top-selling romance novelist. However, being a 'man's man' in the Australian outlook, to avoid embarrassment, he needs a name, a woman's name - and he chooses that of his best friend, Ruby Vale. He must do some fancy footwork to continue the charade when the glamorous city publisher, Ziggy, arrives in dusty outback Lucktown to sign 'Ruby Vale' to a major book deal. Ruby agrees to help Jack though it's for her own gain as well - the publisher will pay for her coming wedding (with Hamish, Jack's buddy). Accompanied by Jack, Ruby goes to Sydney to meet the media, appear on TV and cocktail parties, etc. Gradually, Jack realizes that he has fallen in love with Ruby, while Ruby is also touched by Jack's novel. However, Hamish arrives in Sydney a few days later and asks both of them to stop all these foolish things...

在一所由才华横溢、富有远见的史蒂夫·艾纳斯蒂（克里斯·海姆斯沃斯饰）管理的先进监狱里，囚犯们佩戴着一种通过外科手术连接的装置，通过该装置注射一定剂量改变心智的药物，以换取减刑。没有酒吧，没有牢房，也没有橙色囚衣。在“蜘蛛头”中，被监禁的志愿者可以自由地做自己。直到他们最终失去自我。有时候，他们还会变成更好的自己。需要放松？有一种药物可以治疗。不知所措？也有一种药物可以治疗。但当两个实验对象杰夫（迈尔斯·特勒饰）和丽姿（朱尼·斯莫利特饰）建立情谊后，他们的救赎之路跌宕起伏，因为艾纳斯蒂的实验开始完全突破自由意志的极限。 　　《蜘蛛头》改编自乔治·桑德斯的《纽约客》短篇小说，由约瑟夫·科辛斯基（《创：战纪 TRON》、《壮志凌云：独行侠》）执导，瑞特·里斯和保罗·韦尼克（《死侍》、《丧尸乐园》）担任编剧，是一部风格迥异、黑暗搞笑的心理惊悚片。
