Redshirts

Set in the 25th century, "Redshirts" follows the adventures of five new recruits on the Starship Intrepid who come to realize that the ship’s crewmembers are dying at an alarming rate. Their investigation leads to the mind-bending discovery that a science fiction television show, produced in the early 21st century, has somehow “intruded” upon their reality and “warped” it. In other words, the lives of the crew are following the course of a television narrative over which they have no control. (Source: Deadline.com)
