December 1966. Change is in the air as winter's chill grips Oxford. Plans to build a new police station lead both DC Endeavour Morse and DI Fred Thursday to question their respective places on the force. A brace of cases occupy the young detective's time: a boy, Tommy Cork,
reported missing from a broken home, and the body of a washed--up journalist, found on railroad tracks in mysterious circumstances. The
cadaver is that of Eric Patterson -- a disreputable reporter last seen embroiled in an altercation with a high--ranking Council official. Their
topic of conversation? Landesman Construction, a company with hasty plans to redevelop the site of a long--since shuttered boys' correctional facility, Blenheim Vale. When a petty criminal absconds from an open prison, also with a connection to Blenheim, it sets off a
chain reaction of troubling events, threatening to expose unspeakable horrors of the past. The investigation deepening, Endeavour and Thursday find themselves confronted by a cone of silence, and a disparate group of men unwilling to talk. Increasingly on the outs at a police force tainted with cronyism and corruption, the two men must band together, peeling back layers of malfeasance extending to the upper echelons of Oxford society. When it transpires Tommy Cork's disappearance is part and parcel of the same case -- the boy possibly witness to an event others would kill to conceal -- Endeavour and Thursday steel themselves for a reckoning in blood, as Series 2 builds to its hunderous, irrevocable conclusion.
