Please help improve it by removing unnecessary details and making it more concise. (November 2015) (Learn how and when to remove this template message) In 2009, a plague caused by an infected vampire bat has transformed most of the world's population into vampires and due to this event, control of the world no longer belongs to humans. The vampires are incapable of aging or dying from natural causes, but are unprotected against sunlight or any ultraviolet light. The entire vampire world is active at night, and various technological and architecture advances are made to adjust the populated areas to vampires' night cycle (such as UV protective cars, underground railways and paths across the cities, and UV warnings). However, human numbers quickly dwindle, and the need for blood becomes desperate. When deprived of blood for extended periods, vampires degenerate into "subsiders," psychotic bat-like creatures who lose their memories and independent thought and are left with the basic need for blood. Humans are captured and harvested in laboratory farms while scientists research a synthetic blood substitute to satisfy vampires' blood hunger across the world, while animal blood is also widely used. In 2019, Edward Dalton (Ethan Hawke) is the head hematologist for the pharmaceutical company Bromley Marks, the largest supplier of human blood in the United States. Along with fellow hematologist Christopher Caruso (Vince Colosimo), Dalton is in the process of developing a substitute to bolster dwindling blood supplies and to create a substance that can replace blood and be generated as required. The need is underscored after Dalton's boss, company owner Charles Bromley (Sam Neill), reveals that the estimated human population is down to 5%, and national blood supplies will not last more than a month. Faced with this knowledge, Edward and Chris carry out a hasty clinical trial of the latest revision on a volunteering soldier, which is a spectacularly...

Please answer this: Generate a question that has the following answer: Natasha for the following movie plot: Alba (Elena Anaya), a 30-something Spanish tourist in Rome, brings a younger Russian woman Natasha (Natasha Yarovenko) to her hotel room during their last night of vacation in Rome. The details of how they met in a club are left vague. Natasha is at first quite reluctant, insisting she's straight, but the clearly more experienced Alba handles deftly around Natasha's hesitance. Flattered and tempted by Alba, Natasha responds to her sexual advances, but continues to maintain that she is straight and has never had sex with a woman. Alba counters by claiming that she is a lesbian and has never had sex with a man. Alba and Natasha first get undressed and into bed, but Natasha is still very nervous. Alba suggests that they first lay side by side and only casually touch each other's faces. They do so until Alba becomes so relaxed that she falls asleep. Natasha quietly gets out of bed, gets dressed and leaves the room, wondering what would have happened if she stayed and consummated her curiosity and attraction to Alba. In her rush to leave, Natasha leaves her cell phone behind, and the ring-tone wakes up Alba. Natasha soon returns and asks Alba for her cell phone, but is reluctant to enter the room again. When a passing night-shift waiter named Max passes by, Alba grabs Natasha and takes her back into the room. While talking about the location of Natasha's hotel and looking at an old map of Rome from the 1st century, Alba continues to flirt with Natasha with her naked body. Natasha soon succumbs to her attraction and curiosity towards Alba, leading her to quickly get undressed once again and into bed where she and Alba have sex for the first time. Over the next 10 hours, Alba and Natasha grow closer to each other as Natasha becomes more relaxed and comfortable around Alba with their lovemaking. Alba and Natasha share stories, periodically stopping to illustrate their points with pictures on the Internet, talk about the artwork in the hotel room, and explore each other's nude bodies through sex. Alba first tells a...

input question: Generate a question that has the following answer: From Queenan's Diary for the following movie plot: As a child, Colin Sullivan (Damon) had been introduced to organized crime by Irish-American mobster Frank Costello (Nicholson) in the Irish neighborhood of South Boston. Over the years, Costello grooms him to become a mole inside the Massachusetts State Police, until Sullivan is accepted into the Special Investigations Unit, which focuses on organized crime. Before graduating from the police academy, Billy Costigan (DiCaprio) is recruited by Captain Queenan (Sheen) and Staff Sergeant Dignam (Wahlberg) to go undercover, as his family ties to organized crime make him a perfect infiltrator. He drops out of the academy and does time in prison on a fake assault charge to increase his credibility. Each man infiltrates his respective organization, and Sullivan begins a romance with police psychiatrist Madolyn Madden (Farmiga). Costigan is seeing her under the terms of his probation, and they begin a relationship, too. After Costello escapes a sting operation, each mole becomes aware of the other's existence. Sullivan is told to find the "rat" and asks Costello for information to identify the informer. Costigan follows Costello into a porn theater, where Costello gives Sullivan an envelope containing personal information on his crew members. Costigan chases Sullivan through Chinatown. When it is over, neither man knows the other's identity. Sullivan has Queenan tailed to a meeting with Costigan on the roof of a building. Queenan orders Costigan to flee while he confronts Costello's men alone. The men then throw Queenan off the building to his death. When they exit, Costigan pretends he has come to join them. Television news reveals that crew member Delahunt (Rolston) has been an undercover cop, working for the Boston Police Department. Dignam resigns rather than work with Sullivan, who he suspects is the mole after he is asked why he had Queenan followed. Using Queenan's phone, Sullivan reaches Costigan, who refuses to abort his mission. Sullivan learns from Queenan's diary of Costello's role as an informant for the...???
