Task: Question Generation
Input (English): In New York City during the middle of a hot summer, body parts of men are showing up in the Hudson River. The police suspect it to be the work of a serial killer who is picking up homosexual men at West Village bars like the Eagle's Nest, the Ramrod, and the Cock Pit, then taking them to cheap rooming houses or motels, tying them up and stabbing them to death.Officer Steve Burns (Al Pacino), who resembles the victims, is sent deep undercover by Captain Edelson (Paul Sorvino) into the urban world of gay S&amp;M and leather bars in the Meatpacking District in order to track down the killer. He rents an apartment in the area and befriends a neighbor, Ted Bailey (Don Scardino), a struggling young gay playwright. Burns's undercover work takes a toll on his relationship with his girlfriend Nancy (Karen Allen), due to both his refusal to tell her the details of his current assignment and Burns building a close friendship with Ted, who himself is having relationship problems with his jealous and overbearing dancer boyfriend Gregory (James Remar).Burns mistakenly compels the police to interrogate a waiter, Skip Lee (Jay Acovone), who is intimidated and beaten to coerce a confession before police discover Skip's fingerprints don't match the killer's. Burns is disturbed by this police brutality, and tells Captain Edelson he didn't sign on for this so that they can arrest anyone just because he's gay. Exhausted by his undercover assignment, Burns is close to quitting, but is convinced by Edelson to continue with the investigation.Following a new lead, Burns investigates Columbia University students who studied with one of the previous victims, a college professor. At the film's conclusion, Burns thinks that he has found the serial killer, Stuart Richards (Richard Cox), a gay music graduate student with schizophrenic disorder who attacks him with a knife in Morningside Park. Burns brings the man into custody, but shortly afterward Ted's mutilated body is found. The police dismiss the murder as a lover's quarrel turned violent and put out an arrest warrant for Gregory, with whom Burns earlier had a fight over his relationship with Ted.With the police under the impression that the murders have been solved, Burns moves back in with Nancy. In an ambiguous finale, Burns begins shaving his beard in the bathroom while Nancy secretly inspects clothes that he left on a chair: a leather peaked cap, aviator frames, and a leather jacket that all look very similar to the outfit the killer wore. Burns, meanwhile, wipes off his shaving cream and looks directly at the camera.
Output (English): Who investigates Columbia University students?
