Grunge rocker Blake escapes rehab and walks home through a long forest, also swimming through a lake then lighting a fire for the night. The next day, he gets home and changes his clothes. He walks around in the house with a shotgun pointing it at his sleeping roommates Scott, Luke, Asia, and Nicole. He is greeted by Yellow Pages representative Thadeus A Thomas who talks to him about placing an ad in the upcoming book. He receives a phone call from his record company telling him that he and his band have to do another tour and that it is important they make the booked dates, but Blake hangs up. He goes upstairs and falls asleep on the floor in one of the rooms. Asia awakes and finds him asleep as two boys arrive at the door. Scott and Luke answer the door and the two boys talk to them about their church down the street. Blake changes into different clothes and leaves the house for the shed outside as the Christian boys leave.
Scott, Luke, Asia, and Nicole leave and Blake goes back into the house. His friend Donovan and a private detective come to the house and Blake leaves as they look around the house for him. He waits for them to leave before he enters the house again. He messes with the guitars and drums putting them on loop with his vocals. He stops when his record executive (Kim Gordon) comes over and tries to have him leave with her but Blake refuses. Blake goes to a rock club that night where a friend of his comes up to him and tells him about how he went to a Grateful Dead concert. Blake leaves before his friend can finish telling the story. Blake goes back home where Scott takes some of his money and Luke asks help from Blake on a song.
Scott tells Luke that Donovan had a private detective with him and that they should leave. After Scott and Luke have sex with each other upstairs, Blake plays acoustic one last time before walking out to the shed where he sits quietly, watching his roommates leave. They spend the night at their friend's house, and awake the next morning to see the news announcing that Blake committed suicide and an electrician found his body. Scott, Luke, and Nicole get in a car and leave, driving down a highway while Luke plays the guitar in the back seat.Michael Pitt as Blake

Last Days is the third and final installment in what Van Sant has frequently called his "Death Trilogy", which began with Gerry (2002) and continued with Elephant (2003). The dialogue and narration in all three films are minimal, and scenes do not proceed linearly. As in Elephant, scenes are revisited from new angles, starting at differing points in time, without a signal to viewers that the clock has been turned back and a previous scene is being revisited. In a later film, Paranoid Park (2007), Van Sant uses the same technique. Also as in the other films, many of the actor's character names are the same as their actual first names.
Van Sant has stated he had contemplated the project for nearly a decade. At one time, he wanted to do a biographical film about Cobain but decided against the idea out of concern over the potential of a lawsuit by Cobain's widow, Courtney Love. Van Sant was unsure how Cobain's fans and family would react to Last Days; he spoke to Love several times over the years about his project and recently expressed his concern that it might be painful for her to see the film. Actress Asia Argento, who plays a character reminiscent of Jessica Hopper (Michael "Cali" Dewitt's girlfriend) in the film, stated, "It's been written that I play Courtney Love, and it's not true. I'm so upset. I don't know why people say that. I feel very sorry for her. She's been demonized and I feel sorry for anybody that's lost like that. But no, I play a character that's very dorky."
Last Days features two original compositions by Michael Pitt: an acoustic song entitled "Death to Birth" and an electric jam called "That Day". Lukas Haas composed another piece, "Untitled". Rodrigo Lopresti composed "Seen as None" and "Pointless Ride". The character Scott listens to "Venus in Furs" by The Velvet Underground. Blake, in one scene, watches the music video for "On Bended Knee" by Boyz II Men on television. "Venus in Furs" contains the lyric "...on bended knee". A soundscape piece called "Doors of Perception" ("Türen der Wahrnehmung") was composed by Hildegard Westerkamp.
The film was shot in the Hudson Valley region of New York, which, due in part to cinematographer Harris Savides' specialized treatment of the film stock, suggests the Pacific Northwest, where Van Sant is from.
Last Days received mixed reviews, including from The Village Voice and The New York Times. It currently holds a 57% approval rating on the website Rotten Tomatoes, but a 67/100 on Metacritic.
The film was entered in the 2005 Cannes Film Festival where it won the Technical Grand Prize. It was nominated for an Independent Spirit Award for Best Cinematography, but failed to win any awards at the festival.
