When a Stranger Calls

I used to babysit a lot until I saw this movie. "When a Stranger Calls," is about a young girl who goes to babysit in a large deserted house and gets stalked by a serial killer. She is just your average teenager who agrees to babysit young kids. However, she continuously gets a call saying, "Check the children." She goes around checking the house and finds the nanny dead and her best friend dead. In the end, it is up to her to fufill her obligation and protect the children she was trusted with. The entire movie was very well put together and very suspisious. In the end the serial killers identity is never revealed.
