Taking place after the events of the series finale of the New Who era, we have The Thirteenth Doctor getting a distress signal from a planet named Regulon 7. Along with her companions, a human teenager named Tara, as well as a 400 year old alien named Nox, she goes and tries to figure out what is going on, on the planet. When they land, they see the planet abandoned, and have to figure what happened and who sent them the distress call. What they find, is a bug-like creature called a Popln who claims he has murdered every being on the planet. It's then that he kills both of The Doctor's companions and The Doctor herself. She is then regenerated into a new body, and while trying to figure out the new ins and outs, has to figure out the mystery of what happened to Regulon 7. Would be a theatrical horror sci-fi film reminiscent of movies like Alien.
