conversations.value: City of the Lost: At age eighteen, Casey Duncan is attending police college to become a detective, much to the disapproval of her parents, who are both prominent doctors.\nShe is dating Blaine Saratori, a small-time drug dealer who brags he is the grandson of a mobster in Montreal.\nHer high school friend Diana is attending a nearby community college and living with her.\nOne night as Casey and Blaine cut through an alley after leaving a bar, several gang members attack them and accuse Blaine of trespassing on their turf.\nAfter their leader threatens Casey, she disarms them, expecting Blaine to grab the gun so they can escape.\nInstead, he runs away and she is presumably raped after being beaten unconscious.\nSeveral weeks later, after waking from a four-day coma, Casey seeks out Blaine who she blames for leaving her for dead and not calling the police, as she was only found hours after the attack by a drunken stranger.\nHe has since denied abandoning her, claiming they split up.\nWhen he continues to refuse to apologize or take responsibility for his actions, she shoots him in the heat of the moment, killing him.\nAfterwards, she throws away the gun and calls 911 anonymously, giving a description of the gang members.\nShe is never caught.\nTwelve years later, Casey is a detective with the Special Victims Unit.\nHer parents died in a small plane crash years ago.\nShe has developed a bizarre game of Russian roulette in which she tells her therapists what she has done, believing that if she deserves to be caught, she will be.\nCasey is still friends with Diana, as their relationship was strengthened after Diana remained with her after her attack and has kept the secret of Blaine\'s murder since she confessed after Diana found her changing out of her bloodstained clothing.\nDiana has since married and divorced Graham Berry, her abusive ex-husband, a respected lawyer and "brilliant psycho," who often beat Diana, once attempting to kill her.\nCasey moved with Diana when she relocated to escape him and is in a relationship based on casual sex with an ex-con bartender named Kurt.\nOne night at his bar after work, Diana tells Casey that Graham is in town in business and sought her out, trying to convince her to return to him and asking her to dinner.\nHer arm is badly bruised from where he grabbed her in the parking garage afterwards.\nCasey finds Graham the next day and warns him to stay away from Diana, threatening him with a statutory rape charge from his past.\nConvinced she has scared him off after Diana tells Casey he has left, Casey instructs Diana to lie low and stay in her apartment for the next few days.\nDiana tells Casey of a town she has heard about where people who wish to disappear can go, located deep in the Yukon wilderness and completely off-the-grid.\nCasey dismisses it as an urban legend, but Diana insists it is real.\nShe spends that night with Kurt, who has been getting strange phone calls he believes are connected to his life as a criminal.\nThat combined with Casey believing someone is stalking her prompt her to follow after Kurt when he leaves at two in the morning to make a deposit.\nShe narrowly saves him; a man shoots him in the shoulder, telling him he was sent by mr Saratori before running away.\nHe is hospitalized but in no serious danger and Casey realizes that her most recent therapist must have told someone what she had done and Blaine\'s grandfather, Leo Saratori is after her.\nWhen she returns to her apartment, she finds Diana badly beaten.\nShe claims Graham returned and hurt her in return for Casey\'s threats.\nCasey agrees to let Diana look into the mysterious town and they are soon contacted by its members, who instruct them to send identification and information and evidence on their situation for an extensive screening process to be granted admission.\nA few days later they meet with two people: a secretarial woman named Val, and a man from the town\'s local law enforcement who demands to interview Casey separately.\nThe reason she and Diana were ever considered, he tells Casey, is because he is the sheriff and is in need of a detective.\nBut he has figured out that she is responsible for Blaine\'s murder and does not want her; furthermore he does not believe Diana\'s story.\nEventually, Casey convinces him to agree to a deal: if he allows them into the town, she will leave as long as Diana is allowed to stay.\nThey are given four days to create fake trails before their disappearance.\nDiana leaves before Casey, who spends a last night with Kurt at an inn, where he gifts her a necklace.\nShe leaves a note for him before she leaves to meet the sheriff.\nHe finally introduces himself as Eric Dalton and reiterates their deal: she will stay six months in the town, which he calls Rockton, otherwise the Council will not let Diana in, as she isn\'t useful.\nThey drive for several hours before flying in a plane, which he pilots himself.\nNo contact is allowed while they are in Rockton; Casey\'s cell phone is confiscated and she is disallowed to answer a last message from Kurt.\nWhen they arrive in Rockton, Casey immediately meets several residents of the town.\nWill Anders is Dalton\'s handsome and friendly deputy, a former soldier who takes an immediate shine to Casey.\nBeth Lowry is the town doctor and Isabel owns the Roc, a local bar.\nSeveral residents of Rockton abuse a locally manufactured drug called rydex, as Casey learns.\nDalton believes Hastings, a chemist in the town is responsible for making it more addictive.\nMeanwhile, the body of a missing man, Henry Powys is found in the woods, missing its legs.\nInitially, it is believed animals were responsible but it is soon determined the legs were hacked off by a human.\nCasey is reunited with Diana who has become much more cheerful since she arrived in Rockton.\nShe is partying, mingling, and even dating a few men in town as men outnumber women three to one.\nBecause of the high concentration of men compared to women and the fact they live in such an isolated environment, rates of sexual assault are high.\nHastings is seen walking into the forest before going missing and Casey, Dalton, and Anders hunt the forest for him.\nThey find a skull nailed to a tree, but no sign of Hastings.
