On the set of "Stab 3," cast members start dying in the order that they die in the script. There are three different versions of the film script, and they admit they do not know which script the killer read, which means they also don't know which character dies next, as each version of the script has characters die in different order. Every time a cast member dies, a photo of Sidney's mother is left behind. The head of the production company releasing the film (Lance Henriksen) decides to close down the film in hopes of stopping the killer. Unfortunately, the masked killer is now stalking Sidney, who, with the help of Gail and Dewey, and a few cast members from "Stab 3," tries to reveal the killer's true identity once and for all. well done wes u made a good sequal i enjoyed this one better than the other two.
