Flatline is a mission in Grand Theft Auto IV given to protagonist Niko Bellic by the Pegorino Crime Family boss Jimmy Pegorino from his mansion in Westdyke, Alderney.
Niko meets Jimmy Pegorino at his mansion in Westdyke, Alderney, where Pegorino, extremely paranoid, aims a shotgun at Niko, threatening to kill him, but Niko calms him down and tells him to explain what is going on. Pegorino explains that Anthony Corrado, one of Pegorino's guards, is actually an undercover agent working with the Alderney State Police and the FIB, who was hired by them to sell out Pegorino in exchange for freedom. Pegorino continues that he called him and threatened him, which resulted in Corrado suffering a . Pegorino explains that he believed Corrado died, but now knows that he survived and is being treated at the Westdyke Memorial Hospital. Pegorino wants Niko to kill Corrado, but warns him that Corrado's ward is under heavy police protection due to him being a witness.
Niko heads to the Westdyke Memorial Hospital in Alderney to get rid of Corrado. Niko can walk through the reception and spot an unused set of hospital scrubs in a locker room. He changes into them and heads towards Corrado's ward.
Niko arrives at the ward to find a police officer standing outside Corrado's room and another FIB agent at his bedside. Niko persuades both of them to leave, before discretely disconnecting Corrado's life-support machine and leaving the ward. A short time later, a police officer returns to Corrado's room and discovers him dead. Niko is suspected, and soon finds himself surrounded by police officers when he reaches the reception. Niko fights his way out and flees the hospital.
There is an alternative way, where Niko can storm the hospital and silence Anthony, but it is very risky, despite it being quick.
After losing his two-star wanted level, Niko phones Pegorino and informs him of Corrado's death, with Pegorino hoping that nobody else will try to testify against him.
