The Chronology Protection Case (2013)

When Phil D'Amato takes a call from a lady physicist about her missing husband, he has no idea that her life, his life, and every other scientist working on a top-secret time travel project will soon be in dire jeopardy. As the number of dead begins to mount, D'Amato starts to realize that the suspect is not any one person or group but something much more sinister and dangerous.
