Travis Bickle (Robert De Niro) “God’s lonely man” decides it's time to do something about Matthew “Sport” (Harvey Keitel) “the pimp” who pimps out 12-year-old “runaway hooker” Iris “Easy” Steensma (Jodie Foster).
Travis jumps into his cab, speeds over to the pimp's hangout, and shoots him at point blank range before walking over to the shady building/“hotel” where Iris takes all her clients.
When the creepy hotel “clerk” tries to stop him, Travis shoots off the man's fingers, then a not-yet-dead Sport walks in and puts a bullet in Travis' neck, the Vietnam veteran vigilante turn around and empties an entire gun into the pimp's body.
And when Sport's big-time Mafia boss blasts Travis in the shoulder, the taxi driver whips out a hidden gun and sends a lot of lead into the crime boss's face, who falls back pulling down the beaded curtain into Iris’s room.
The “clerk” tries to fight inside Iris’s room Travis pulls a knife taped to his boot and stabs him in the fingerless hand, and executes him with a shot to the head, despite terrorized 12-year-old Iris’s screaming and crying at Travis “don’t shoot him”.
Travis puts a pistol under his chin. But when the hammer comes down, there's nothing but a click. Travis is all out of bullets. Travis collapses on the couch.
The cops show up and find Travis, drenched in blood and smiling from ear to ear. The taxi driver puts his fingers to his head and mimes suicide, and that's when the camera pans out of the room, the overhead camera showing us all the carnage that Travis has wrought.
Well, after the shootout, the film jumps forward in time, and we see Travis' apartment. His wall is covered in newspaper clippings with headlines that read "Taxi Driver Battles Gangsters" and "Taxi Driver Hero to Recover." And as the camera pans across the room, we hear voiceover narration from Iris' dad reading a letter to Travis and thanking the man for rescuing his daughter. He even lets Travis know that Iris is back in school and "working hard."
Then, in the final few minutes of the film, Travis and Betsy (Cybill Shepherd) a Presidential hopeful campaign manager, who had rejected him before, reunite.
she actually seeks out a ride from him in his cab.
She climbs into the back of his cab and asks how he's doing. Travis doesn't have much to say, but after dropping her off, he doesn't let her pay for the ride. Instead, he just smiles and rides off into the darkness of New York City.
