Output: In October 1969, firefighter Frank Sullivan Quaid dies in a warehouse fire, leaving behind his wife Julia Elizabeth Mitchell and sixyearold son John. Thirty years later, in 1999, John Caviezel, now an NYPD detective, is dumped by his girlfriend Samantha for being emotionally shut off. Johns childhood friend Gordo Noah Emmerich finds a Heathkit singlesideband ham radio that once belonged to Frank, but fails to get it working. The night before the anniversary of his fathers death, John is surprised to find the radio broadcasting during an occurrence of the aurora borealis, and has a brief conversation with another man concerning the 1969 World Series, which John is able to recount in specific detail. Eventually, he realizes that the other man is Frank and tries to warn him of his impending death. The next day, while attempting to rescue a young girl, Frank heeds his sons warning and manages to escape the warehouse. That evening, the two reconnect and learn a great deal about each others lives. Subsequently, John begins to notice major changes in the present: His mother Julia no longer lives at her current address, Samantha doesnt recognize him, and he learns that Frank died in 1989 from lung cancer. His boss, Sgt. Satch DeLeon Andre Braugher, assigns him to investigate the Nightingale, a serial killer who murdered three nurses in the 1960s. However, John discovers that the Nightingale is now connected to ten murders, including that of his mother two weeks after Franks nowavoided death. Feeling guilty that their actions somehow led to the Nightingale committing more murders, John persuades his father to help him prevent these crimes from occurring. Frank manages to save the first victim. But when he tries to rescue the second, the Nightingale subdues him, steals his drivers license, and plants it on the victim to frame Frank for the murder. When Frank shares his experience with his son, John realizes Franks wallet has the Nightingales fingerprints. John instructs his father to wrap his wallet in plastic and hide it somewhere in the house where John can find it 30 years later. Using the preserved fingerprints from the wallet, John identifies the Nightingale as Jack Shepard Shawn Doyle, a former detective. In the original timeline, Shepard died from a medical error the same night Frank died. But since, in the new timeline, Julia didnt leave the hospital early after learning of Franks death, she was at the hospital and prevented the error that would have killed Shepard. Meanwhile, Frank is approached by thenDetective Satch DeLeon who tries to arrest him on suspicion of murder. Later, in an attempt to prove his innocence, Frank is able to predict various aspects of the 1969 World Series to Satch, including the infamous Game 5 shoe polish incident. In the resulting struggle, the radio is knocked over and sustains damage, shutting it off. While awaiting questioning, Frank activates the precincts fire sprinkler system, escapes, and breaks into Shepards apartment, where he finds jewelry taken from the victims. Shepard catches Frank in the act and pursues him, ending with a fight underwater where Frank appears to have killed Shepard. Frank fixes the radio, but while talking both he and John are attacked by the 1969 and 1999 versions of Shepard. Using a shotgun, Frank manages to blow off Shepards right hand in 1969, causing Shepherds hand to disappear in 1999 just as hes about to kill John as the changes in the past affect the present. The timeline rapidly fixes itself in 1999 and an elderly Frank, having quit smoking to avoid his death in 1989, kills Shepard with the same shotgun, and embraces his son. The film concludes with a baseball game including John, Samantha now his wife, Johns young son, Frank, Julia, Satch and Gordo, whos now wealthy on account of having invested in Yahoo! on Johns advice.
