10 Awesome Plot Twists That Totally Saved Awful Horror Movies

10. Don't Hang Up

Don't Hang Up follows Sam and Brady, a pair of teens who make YouTube videos where they prank call people. During one prank, they convince a caller called Mrs. Kolbein that an intruder is in her house. When this prank goes viral, the channel blows up in popularity.

One day, a man called Lee rings Sam and Brady, informing him that he'll destroy their lives unless they do as he asks. He then performs his own pranks, which mostly involve killing the YouTubers' friends.

Because Lee comes across as a textbook wacko, it's easy to assume there's no rhyme or reason to his actions. But when Sam encounters Lee in the climax, he discovers he's not the monster he thought he was.

Lee explains how the call Sam made to Mrs. Kolbein (who's implied to be his wife) ended in tragedy. Before Kolbein realised the call was a gag, she shot the supposed intruder, unaware it was her daughter. Devastated that she killed her child, Kolbein blew her own brains out. Because Sam and Brady suffered no punishment for their actions, Lee was compelled to take matters into his own hands.

Now, no one is going to pretend Don't Hang Up isn't full of plot holes - why wasn't Sam and Brady prosecuted for manslaughter? - nevertheless, this twist helped turn a despicable villain into a surprisingly sympathetic character.
