"Class" is a British science fiction drama and a spin-off of the iconic "Doctor Who" series. Set in London's Coal Hill Academy, the show centers on a group of students and their teacher, Miss Quill, played by Katherine Kelly. These characters are thrust into the role of defending their school—and the world—from alien threats that emerge through fractures in time and space. The series skillfully combines elements of teen drama with high-stakes science fiction, exploring themes of friendship, identity, and responsibility. The main cast includes Greg Austin, Fady Elsayed, Sophie Hopkins, and Vivian Oparah, who deliver compelling performances as students navigating both typical adolescent challenges and extraordinary dangers.
