洛拉和朋友从外面回到画室，发现自己的丈夫画家哈维尔倒在了血泊中。警方很快来到了。丽芙梦到了一个僵尸，她不确定那个僵尸是不是真的存在。她告诉拉维，拉维却丢给她一本关于性爱的书，看着这个书，丽芙脑子里看见了死者和另一个女人外遇的情景。巴比诺听了拉维的话，找死者的妻子了解情况。

丽芙惊奇地发现，那个小三正光明正大地站在洛拉旁边！而洛拉竟然知道丈夫外遇的事，而且她不介意。两人震惊了。妻子竟然可以容忍丈夫的外遇。巴比诺收到拉维发来的信息凶手惯用右手，身高应该在187到190之间。丽芙回到验尸间，拉维给她介绍了一位新朋友吉米，是警方的素描专家，丽芙可以让他画出梦里的那个僵尸。

吉米一边画一边听丽芙描述，但丽芙总觉得吉米画的不对，最后她抢过画笔自己画了起来，看来她吃过哈维尔的脑子后还有了一点画画的技能。她很快就画好了，真的很像。巴比诺审问了洛拉的好朋友菲斯，巴比诺看出他与洛拉有染，而且他的身高是188公分，符合条件，但是他却建议巴比诺查一查被哈维尔睡过的那些女孩的男朋友。丽芙发现梦里的那个僵尸来到了验尸间，他就是那个把丽芙变成僵尸的人！而且丽芙还看见他追着死者跑。但是僵尸解释说是死者抢了他的钱包他才追的。

僵尸不小心将托盘弄到了地上，这个场景又让丽芙看见了死者的一些事：塔沙的男友抓住了塔沙和哈维尔偷情，很生气。巴比诺审问了前男友，他没有案发时的不在场证明而且他的身高也符合条件。但是他也说出了哈维尔染指菲斯的女儿贝卡，真是个滥情的家伙。僵尸在酒吧成功的搭讪了一个女人，两个上床了，他把她也变成了僵尸。第二天僵尸又来找丽芙，他告诉丽芙自己已经在慢慢改变了，不再是以前的那个自己了，她已经和以前的人和事有了一个决断，而丽芙很容易能得到人脑，希望她可以分他一点。丽芙答应了他下班以后给他送去，可是当丽芙找到他时发现他正在和以前的不三不四的朋友纠缠，生气地离开了。丽芙没有看到，那些人硬要把僵尸带上车，于是他杀了他们得到了他们的脑子。他带着脑子去找昨天和他在一起的女人，用人脑威胁她给他钱，为了人脑她只好照做。

巴比诺来找丽芙要她和他一起去看哈维尔的作品展，就在哈维尔住的那个阁楼上。巴比诺还得到一些线索，菲斯当天曾离开餐厅去取钱，而银行离阁楼很近，但是菲斯已经破产了，银行账户里已经没钱了，看来他的嫌疑很大。来到阁楼丽芙没有看那些画作而是直接来到地下画室，那里还有很多画，突然她看见了一幅画，画面又涌入了脑海：怀孕的贝卡对哈维尔说哈维尔我们马上要有儿子了。

她连忙跑上楼去。而在楼上巴比诺还在质问洛拉为什么不坦白菲斯当天离开餐厅去取钱的事，洛拉回答的吞吞吐吐的。巴比诺又去质问菲斯，是不是因为钱杀了哈维尔，丽芙赶来直接说因为哈维尔让贝卡怀孕，所以菲斯怀恨在心。这是拉维过来了说之前认为凶手是比哈维尔高的人，但是如果哈维尔站在楼梯最下方，凶手站在楼梯上向他刺去，那么凶手就只有丽芙那么高。是洛拉！她知道贝卡怀孕哈维尔要离她而去了，所以她杀了哈维尔！案子结束后丽芙找到梅根想要和他和好，当然没有告诉她是僵尸的事实，可是梅根却不愿意了，他赶走了丽芙。丽芙冷静下来也觉得自己的行为太冲动了。

五个月前，丽芙和未婚夫一起去参加一个船上派对，玩的正开心的时候，派对上突然出现了僵尸，丽芙躲闪不及被僵尸抓伤了手臂，她也变成了僵尸，为了保持人性，她不得不时常吃人脑。她没有告诉任何人这件事。

五个月后。丽芙找到了一份验尸官的工作，这很方便她吃人脑。家人很不理解，怀疑她还没有从五个月前的阴影中走出来。丽芙来到验尸间发现拉维正在对着一具尸体喝牛奶。这是一具无名女尸，身份不明。拉维接到一个电话匆忙地离开了，四下只剩丽芙一个人，头脑中的欲望越发强烈。她将死者的人脑取出加工成了美味的食物。她正在享受着美味，拉维突然回来了，发现了丽芙的秘密。原来他早就怀疑丽芙了，但是他并不害怕。

巴比诺警官来到验尸间，他负责无名女尸的案子。他晃着手里的手铐，丽芙的脑中闪现了一些画面，是死者的部分记忆！丽芙脱口而出死者叫史蒂芬妮，2008年曾在加拿大因盗窃被捕。巴比诺很好奇丽芙是怎么知道的，为了掩饰真相，拉维只好说丽芙是一名灵媒，巴比诺半信半疑。丽芙来到她母亲的鬼屋帮忙，她看见一个男人吓着了一个女孩，脑海里又浮现了一些画面：死者生前见过强尼，那个著名的天气预报节目主持人！丽芙把这个发现告诉了拉维，拉维让她去告诉巴比诺，以一个灵媒的身份。丽芙来到巴比诺办公室，他不在。丽芙鬼使神差地偷了巴比诺办公桌上的一些东西。过了一会巴比诺来了，丽芙告诉了他，他决定去找强尼。

强尼承认自己认识史蒂芬妮，但是在案发当天他在做节目，全国观众可以作证，他建议警方去调查死者的朋友苔丝。丽芙和巴比诺找到苔丝，苔丝听到史蒂芬妮死了就赶紧关上房门，不再和两人交谈，不过她告诉了两人死者的真名：塔蒂亚娜·库尔萨，凭借这个名字两人找到了死者租的房子。房东打开房门，发现屋子里一片混乱，丽芙看到巴比诺去阳台查看，脑子里又闪现了一些画面，一个男人在阳台上逼问死者什么戒指在哪，得不到回答就杀了死者！等两人再来找苔丝的时候，她已经逃走了，她的邻居说她有一个朋友莫妮卡，可能去了她那儿。

拉维告诉丽芙她可能会治好，她想要将这个消息告诉梅特。可是来到他的家门口她退缩了，尤其是在看见梅特和一个女孩在高兴地玩打僵尸的游戏后。巴比诺正在根据莫妮卡的IP地址追查她的住址却被上司告知案子已经被普拉特警官接手了，普拉特热情地要求巴比诺一起调查。丽芙发现自己虽然改变不了现实，但是可以伸张正义，于是她把偷的东西都还了回去。等她回到验尸间，发现巴比诺也在他告诉她强尼说塔蒂亚娜好像吃了须猪肉。巴比诺好像想到了什么，须猪肉，长着胡须的男人，是普拉特！可是普拉特已经得到了莫妮卡的地址，两个女孩有危险了！丽芙和巴比诺赶紧前往莫妮卡的家。巴比诺将丽芙留在车上，自己去抓普拉特。普拉塔发现了他朝他开了两枪逃跑了。

而丽芙看见普拉特从屋子里逃出来，连忙开车拦住他，他朝丽芙开枪，可是丽芙是打不死的。普拉特开着车逃跑，丽芙一直在车顶阻拦他。终于车停下来，丽芙被甩开了，普拉特晕了过去。这时丽芙僵尸习性出来了，想要吃了他的脑子。幸好巴比诺及时赶到，他没有发现丽芙的不对劲。

丽芙凭借着自己的“优势”抓住了凶手，伸张了正义，而且她似乎在慢慢变好，调整自己的心态。
