ABy the end of the movie, seven characters are dead, starting with the suicide at the beginning of the movie. Of the five people trapped in the elevator, only Tony survives. A mirror breaks and a shard of glass slices Vince's jugular, Jane is hanged from a cable, Ben has his neck broken, and Sarah's throat is cut. Lustig is electrocuted, and repair technician Dwight (Joe Cobden) falls down the elevator shaft. It is also shown in a flashback how Bowden's wife and son were killed in a car accident five years ago.
ATony's fiancee arrives and informs Bowden that his full name is Tony Janekowski. Bowden realizes that they've misidentified Jane Kowski and that she is the unidentified person. As Tony cradles a dying Sarah in his arms, the old woman rises up, her eyes totally black, revealing herself to be the Devil. She informs Tony that it is now his turn to die. Tony flashes back to the hit-and-run accident five years ago in which he smashed into another car, killing a woman and her child, while he was reaching for a beer. He begs the Devil to take him instead of Sarah, but the Devil refuses, so he grabs the walkie-talkie and confesses his crime to Bowden, not realizing that it was Bowden's wife and son he killed. 'Damn,' says the Devil. 'I really wanted you.' Suddenly, all systems come back online, and the firefighters are able to pry open the elevator doors. Tony is taken into custody, but the Old Woman is gone. On their way to the police station, Bowden reveals that it was his wife and child who Tony killed. 'I've been waiting for this moment for fives years,' Bowden says. 'All the things I'd say to you and what I'd do. The thing is...I forgive you.' In a final voiceover, Ramirez says, "After my mother would finish her story, she would always comfort us. 'Don't worry,' she'd say. 'If the Devil is real, then God must be real, too.'"
ANo. Devil is based on a story by Indian-born film-maker M. Night Shyamalan (who also produced the movie) and a screenplay by American screenwriter Brian Nelson. Shyamalan acknowledged that the idea for the story came from British crime writer Dame Agatha Christie's 1939 novel And Then There Were None. Devil is the first story in The Night Chronicles, a trilogy of movies about the supernatural. The second movie is titled Reincarnate. The third movie is yet to be titled.
