Se7en
John Doe is a middle-aged psychopathic serial killer obsessed with the so-called "Seven Deadly Sins." He carefully targets his victims and apparently plans their deaths while cleverly stalking them and by secretly gathering as much of their personal information as possible without getting exposed or caught. He tortures them to death in symbolic murders representing in an attempt (at least in his own mind) to remind the world about the inevitability to avoid these deadly sins that ultimately will lead to their tragic demise either way. His insanity is based on fanaticism and obsession but did little to damage his knowledge; in fact, his madness may have added to it as he is portrayed as a twisted mastermind who is comfortable and very smitten in toying with the authorities. Doe particularly seems to highly enjoy playing mind games with the film's protagonists, Detective David Mills and Detective William Somerset, in a similar fashion to killers such as Jack the Ripper.

Mills and Somerset eventually track Doe to his apartment, unaware that Doe is out at the time. Doe then comes down the corridor and sees the two detectives at his front door, prompting him to fire upon them. Mills chases Doe out of the building but Doe catches him off guard and aims a gun at the side of his head. Mills is unable to identify the killer as his face is shrouded in darkness, but Doe leaves him alive and disappears.

Later, when Mills and Somerset return to the police station, Doe appears to them (having got blood all over his arms and shirt) and intentionally gets himself arrested. The detectives are confused as to why Doe would hand himself in when he is two murders away from completing his "masterpiece", but Doe tells them that there are two more bodies hidden away. He then states that he will show them where the bodies are as long as Mills and Somerset are the only two to accompany him, otherwise he will plead insanity. The detectives agree and Doe directs them in their police car to the location of the bodies. Throughout the journey, Mills desperately and aggressively attempts to understand Doe's reasons for his actions, with Doe calmly stating that God told him to reveal to mankind what an awful and tragic place the world has become.

They arrive in a remote desert area in the middle of nowhere and a delivery van steadily approaches them, alarming Somerset. As he halts the van in its tracks, the driver claims that he was told to arrive at this location at this precise time to deliver a box. While Somerset looks at the box curiously, unsure whether he should open it or not, Doe tells Mills that he admires him. When Mills questions him on this, Doe reveals that he was jealous of his normal life (representing the sixth sin, Envy) and went to visit Mills' wife Tracy, attempting to "play husband" by raping her. Afterwards, Doe decapitated her, and Somerset is horrified to find that the box contains Tracy's severed head. Somerset then realizes that Doe is planning to have himself killed by the hands of Mills (in order to fully complete the seventh and final sin Wrath) to complete his work. Somerset rushes back to Mills in an attempt to prevent him from killing Doe, knowing that is what he wants, but Doe provokes Mills further by telling him that Tracy was pregnant, as she had been keeping it a secret from him. Doe then closes his eyes, awaiting the inevitable punishment for his crimes as Mills (unable to contain his fury of distress over the loss of his wife and potential child) shoots him in the head and then repeatedly to his death (despite Somerset's objections). Despite Doe's death, his plan still succeeds since his masterful manipulation had prompted Mills to complete the seventh sin. Mills later becomes nearly catatonic and is placed under arrest for the murder of Doe, much to Somerset's discomfort.
