Context: John Strangways, the British Intelligence (SIS) Station Chief in Jamaica, is ambushed, killed, and his body taken by three assassins known as the "Three Blind Mice". In response, MI6 agent James Bond (007) is summoned to the office of his superior, M. Bond is briefed to investigate Strangways' disappearance and to determine whether it is related to his cooperation with the American Central Intelligence Agency (CIA) on a case involving the disruption of Cape Canaveral rocket launches by radio jamming.Upon his arrival at Kingston Airport, a female photographer tries to take Bond's picture and he is shadowed from the airport. He is picked up by a chauffeur, who Bond determines to be an enemy agent. Bond instructs him to leave the main road and, after a brief fight, Bond starts to interrogate the driver, who then kills himself with a cyanide-embedded cigarette.During his investigation Bond sees a picture of a boatman named Quarrel with Strangways. Bond locates Quarrel but finds him to be un-cooperative when he interviews him. Bond also recognises Quarrel to have been the driver of the car that chased him from the airport. Bond follows Quarrel and is about to be beaten by him and a friend when the fight is interrupted by the man from the airport who has been following Bond: he reveals himself to be CIA agent Felix Leiter and that not only are the two agents on the same mission, but also that Quarrel is helping Leiter. The CIA has traced the mysterious radio jamming of American rockets to the Jamaica vicinity, but aerial photography cannot see the exact location of its origin. Quarrel reveals that he has been guiding Strangways around the nearby islands to collect mineral samples. He also tells about the island of Crab Key, owned by the reclusive Dr. No, who operates a bauxite mine which is rigorously protected against trespassers by an armed security force and low-scan radar.After finding a receipt in Strangways' house about mysterious rocks naming, Professor R.J. Dent, Bond meets with Dent who says he had assayed the samples for Strangways and determined them to be ordinary rocks. This visit makes Dent wary and he takes a boat to Crab Key where Dr. No expresses displeasure at Dent's failure to kill Bond and orders him to try again, this time with a large venomous spider. Bond survives and kills the spider.Bond becomes friendly with Strangways' secretary, Miss Taro and agrees to meet her at her home in the hills above Kingston. While driving there, Bond is attacked by several men driving a large hearse. He is able to outmaneuver them and the hearse is run off the mountain road and explodes. When Bond shows up at Taro's house, she's surprised to see him, a fact that Bond notes easily. She goes into her bedroom and talks on the phone to her boss, who tells her to keep Bond occupied for a few hours. Bond and Taro spend that time in bed.Bond makes a phone call, ostensibly asking for a taxi but actually talking to the local police, who show up soon after and arrest Taro. Bond then sets a trap for Dent and waits for him to show. Dent steals into the bedroom and fires several silenced shots into the bed, which Bond rigged to look like it was occupied. Bond forces Dent to drop his pistol and begins to interrogate him about Strangways and his radioactive rock samples, which Dent tried to cover up. Dent is able to recover his pistol, finding it empty and Bond coldly shoots him dead.Having detected radioactive traces in Quarrel's boat, where Strangways' mineral samples had been, Bond convinces a reluctant Quarrel to take him to Crab Key. On the beach there, Bond meets the beautiful Honey Ryder, dressed only in a white bikini, who is collecting shells. At first she is suspicious of Bond but soon decides to help him, leading them all inland to an open swamp. After nightfall they are attacked by the legendary "dragon" of Crab Key which turns out to be a flame-throwing armoured vehicle. In the resulting gun battle, Quarrel is incinerated by the flame-thrower whilst Bond and Honey are

Context: Paul Stanton (Mulroney) and his wife Diane (Diane Kruger) are a couple whose daughter is dying from a rare degenerative lung condition. The only thing that can save her life is a lung transplant from an organ donor. The movie starts when the donated lung fails to arrive correctly. The movie goes back and forth between the present and the events leading up to it. In the present day, Paul goes to Juarez, Mexico to find a man called Dr. Navarro. After leaving his cell number at many local hospitals, somebody finally contacts Paul. In the past, Dr. Rubin (Arquette), who's treating their daughter (Stallard), had given them information regarding Paul's associate, Harrison (Shepard), who somehow managed to get an organ transplant for himself, possibly from the black market. Paul confronted Harrison and finally managed to get Dr. Navarro's name from him. Harrison told him that he was contacted by Navarro and he didn't know how to reach him. Back in the present day, Paul is ambushed by a couple of Navarro's guys that tell him to stay away. After an arduous search, Paul finally finds out that Dr. Navarro is actually Dr. Martinez (Perez) from a local hospital that he visited previously for his wounds. Paul confronts Martinez and asks him to find a lung donor for his daughter, who only has one week to live. Martinez agrees to help him for a $250,000 cash payment. The next day, Martinez tells Paul that he has found a matching donor for his daughter. Paul tells Diane to go to Juarez and prepare their daughter for the transplant operation. Little does Paul know that the donor is actually a live person; Martinez and his men have planned a hit-and-run accident to get the lung implant from a local street boy. Paul discovers this fact and tells Diane about it. Diane tells him that she does not want to know where the donor comes from. Paul confronts Martinez at the operating table. Martinez tells Paul to make a choice: to go ahead with the operation or disband the operation knowing that they won't be able to find another match in time to save his daughter's life. The next scene shows Paul and Diane at their daughter's funeral. Diane gives Paul an accusing look blaming him for their daughter's death. Meanwhile, elsewhere, the local boy that was supposed to be the organ donor is alive and playing soccer with his friends.
Question: What illegal operation is Dr. Navarro involved?
