Television writer Daniel Feeld is plagued by severe stomach pains and fierce arguments in the cutting room over his latest film, "Karaoke." He is confused when he overhears a beautiful young woman named Sandra arguing with her boyfriend in what sounds eerily like a scene from "Karaoke." Fiction and reality seem to merge. Is Daniel's mind being addled by drink, or is he going crazy?
Now seriously ill, Daniel has been admitted to the hospital. The plot of his film "Karaoke" still seems to be coming to live around him. Director Nick Balmer is enraged to discover that a real-life gangster with the same name and job as Daniel's fictional villain exists. While Nick is becoming dangerously obsessed with actress Linda Langer, Daniel's relationship with Sandra deepens.
Following the revelation that a real "Pig" Mailion exists, Daniel is reassured that the similarity of his script to real life is pure coincidence. Nick's affair with Linda Langer leads him into a murky blackmail plot, and Daniel learns that Sandra is determined to take revenge on Mailion for his vicious attack on her mother.
Mailion exacts brutal revenge on Nick, who is forced to admit his infidelity to his wife. When Daniel learns that he has only eight weeks to live, the death sentence galvanizes him to take fate into his own hands. Dying, Feeld begins to imagine a final film combining cyberspace, virtual reality and cyrogenics.
