I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Butterfly Effect: Revelation Movie plot: Sam Reide (Chris Carmack) witnesses a woman killed, then wakes up in an ice-filled bathtub, his vitals being monitored by his sister Jenna (Rachel Miner). It is revealed that Sam can travel back to any time and location during his lifetime (occupying his body of that time in his life), needing only to concentrate on where and when he wishes to arrive. He has helped the local police capture criminals under the guise of being a psychic. We learn that Sam pays his sister's rent and buys her groceries, and that she rarely leaves the apartment and lives in squalor in a run-down section of Detroit.That night, Elizabeth (Sarah Habel), the sister of Sam's murdered girlfriend Rebecca (Mia Serafino), arrives at Sam's apartment. She believes that the man about to be executed for her sister's murder, Lonnie Flennonds (Richard Wilkinson), is innocent, and she offers to pay Sam to find the real murderer. Sam turns her down, but goes to speak with the man who tutored him on time travel, Goldburg (Kevin Yon), who reminds him of the cardinal rules: he's not to alter his own personal past, nor travel in time with his body left unsupervised. We learn that a fire that claimed the lives of Sam and Jenna's parents had claimed Jenna's life, but Sam altered time so that their parents died instead. After Goldburg's departure, their buxom bartender Vicki (Melissa Jones) seductively offers Sam a buttery nipple; he and Vicki have sex, but upon seeing Rebecca's photo, he cannot continue.Sam changes his mind and agrees to help Elizabeth out. He tries to help Lonnie without time-traveling, but Lonnie refuses the help, believing Sam to be the culprit. Frustrated, Sam travels back to June 1998. He first runs into a drunk Elizabeth, telling her to stay in her locked car. He goes into Rebecca's bedroom to find her already dead; while there, Elizabeth is attacked from her backseat. Sam returns to the present, to learn he no longer owns a car, is renting his couch to a roommate named Paco (Ulysses Hernandez), and no longer works for the police,... My question: In what city does Jenna live?

Detroit
