After the destruction and rebuilding of Barrow, Alaska, Stella Oleson (Kiele Sanchez) misses her beloved husband Eben and spends her time giving lectures uncovering the truth about the incident in Barrow and the existence of vampires to the world, following the lead of the unknown Dane. In Los Angeles, Stella uses ultraviolet lights in the auditorium to expose the vampires to the audience but the FBI Agent Norris (Troy Ruptash) tells that the incident was a hoax. When Stella returns to the motel where she is lodged, she meets Paul (Rhys Coiro), Todd (Harold Perrineau) and Amber (Diora Baird) that are vampire hunters and leans that Agent Norris is a wannabe vampire and the vampire leader Lilith (Mia Kirshner) is in the city and ready to return to Alaska. Further, she finds that Dane (Ben Cotton) is a vampire that has kept humanity after his transformation and wants to destroy Lilith. Stella joins the quartet that is armed and ready to battle against the evil vampires.
"30 Days of Night: Dark Days" is an implausible sequel of 2007 "30 Days of Night". The incoherent screenplay has many flaws and poorly explains why the group fights with the vampires in suicidal attacks, either on the pitch black of the underground of Los Angeles or in a ship during the night. In the first film, the strength and the speed of the vampires were absurd and now the human can be protected behind a steel door. Kiele Sanchez performs Stella Oleson that was originally performed by Melissa George, and the scene of her final fight with Lilith is a rip-off of "The Descent". The conclusion is ridiculous and with the only intention of giving another sequel. My vote is five.
Title (Brazil): "30 Dias de Noite 2" ("30 Days of Night 2")
