Scream 3 is a slasher horror movie. I bought my copy new.
Review:
Sidney Prescott now lives out in the middle of nowhere, spending as little time with other people as possible. Even her work (crisis hotline) is remote, and she doesn't use her real name with her coworkers. Meanwhile, Cotton Weary is milking his 15 minutes of fame as much as possible and now has his own talk show. He also has a cameo appearance in the newest Stab movie. When he gets a "wrong number" call from a random woman who says she recognizes his voice and is a fan of his, he initially soaks up the attention and ego boost, until the caller reveals themselves to be a new killer using voice changing technology. Whoever it is wants to know where Sidney Prescott is, or they'll kill Cotton's girlfriend.
So yeah, the newest twist on the Scream franchise is that the killer is using voice changing technology to make themselves sound like other people. Phone calls can't be trusted, although lots of people don't find that out until it's too late. Sidney is eventually drawn out of hiding and into the race to find and stop the killer, who is now targeting people involved in the newest Stab movie.
