When a Killer Calls 2006
Plot: Trisha Glass, a young babysitter, is hired to watch a girl in a large, secluded house. As she gets settled in, she begins receiving a series of increasingly threatening and disturbing phone calls. At first, she suspects her boyfriend is playing a prank, but the calls grow more sinister when the killer starts sending her gruesome photos of his previous victims via her flip phone. As the police try to trace the calls, the killer starts to pick off other people around her, all while revealing a horrifying secret: he is already inside the house, and he plans to save her for last.
