In 2011, after a night out with friends, 22-year-old Sian O'Callaghan disappeared. When her worried boyfriend reports her missing, Detective Superintendent Steve Fulcher begins to place together her last movements. Believing Sian may still be alive, Fulcher initiates an urgent full-scale search operation and edges closer to a chief suspect, local taxi driver Christopher Halliwell. However, once under arrest, what Halliwell has to say steers the investigation in a completely unforeseen direction, leaving Fulcher on the precipice of a life changing choice between protocol and justice.

A Confession raises important questions on how we want our police to behave--should Fulcher be praised as a courageous officer fighting for the life of a missing woman or punished for riding roughshod over the law?
