Before Inspector Morse, there was the rookie Constable Morse, fed up with police work and ready to nip his career in the bud by handing in his resignation. That is, until a murder turned up that only he could solve. Shaun Evans (The Take, The Virgin Queen) returns for a second season as the young Endeavour Morse, before his signature red Jaguar but with his deductive powers already running in high gear. When an elderly man is murdered with a ceremonial dagger, Morse's investigation leads him to an isolated and dreary school for girls. Digging into the school building's disturbing history, he learns of a series of murders that took place almost 100 years before to the day. As the centenary approaches, Morse races to prevent the ghosts of the past from crashing into the present.
