Dr. Alexandre Beck has been slowly putting his life back together since his wife, Margot, was apparently murdered by a serial killer using wild attack animals eight years before. However, Alex finds himself implicated in a double homicide – even though he knows nothing of the crimes. The same day, he receives an email that appears to be from Margot, which includes a link to surveillance footage that shows his wife looking alive and well; the message warns Alex that they are both being watched. As Alex struggles to stay one step ahead of the law, henchmen intimidate his acquaintances into telling them whatever they might know about him, eventually killing a friend named Charlotte. In the meantime, Alex's lesbian sister Anne persuades her well-off partner Hélène to hire a respected attorney, Élisabeth Feldman, to handle his case.

Margot attempts to arrange a meeting with Alex by sending him an email that he must read in an internet café to avoid being spied on. Before this meeting can take place, a warrant is issued for Alex's arrest for Charlotte's murder. Alex goes on the run whilst his friends and lawyers struggle to find out the truth about the murder and Margot's reappearance. As he is being pursued by police, Alex is rescued by Bruno, a gangster from a rough part of the city who feels he owes Alex a favor. The mysterious henchmen reappear to prevent Alex's meeting with his wife, but he is rescued once again by Bruno. Margot is seen almost escaping on a flight to Buenos Aires. Élizabeth proves that Alex has an alibi for Charlotte's murder thanks to eyewitness accounts at the internet café.

Alex notes the numerous mysteries about his wife's death – mysterious photos of her covered in bruises and traces of heroin in her body. He soon discovers that Margot's father Jacques Laurentin faked her death: she had discovered that Philippe Neuville, the young son of a local aristocrat and governor Gilbert Neuville, was a pedophile rapist whose activities were covered up with help from local police; when she confronted him, Philippe beat her, causing the bruises. Jacques explains that he walked in on the beating and shot Philippe. Gilbert Neuville hired thugs to kill Margot via a phone call. Having tapped the phone call, Jacques doubled the payout for one of the thugs in order to get him to abduct his daughter, kill the other thug and knock Alex out. After shooting the second thug and burying both, Jacques used the body of a dead heroin addict to stand-in for Margot, which was then cremated, and Margot spirited into exile. Furthermore, Jacques reveals that Alex's father who works as the horse rancher for the Neuville family was also murdered for uncovering Philippe Neuville's abuses before Margot did. Jacques apologizes and gives Alex a document compiling the evidence of the Gilbert family's crimes.

Police, listening in on the confession, move to arrest Jacques, but he shoots himself dead as Alex leaves. Keenly aware of the wire, he blocked the bug's transmission to reveal Alex the last piece of the truth: it was Margot who shot Philippe after he beat her; Jacques was covering up her crime, not his. Subsequent to Margot resurfacing, Neuville hired assassins to torture Alex into revealing her location to avenge his son. Neuville Sr is arrested, and Alex and Margot reunite at the lake where their ordeal took place, revealed as the place where they also fell in love as children.

The script made several alterations to the book; a torture expert changed from an Asian male to a white female, and the identity of the killer was switched. The book's author was quoted in an interview as saying that the film's ending was better than his original ending.^[4]

Tell No One was well received both critically and commercially.

Academy Award-winning British actor Michael Caine said of the film it was the best he had seen in 2007 on the BBC's Film 2007 programme. He also included it among his Top Ten movies of all time in his 2010 autobiography, The Elephant to Hollywood.^{[citation needed]}
