Marking the 25th anniversary of the very first episode of Inspector Morse, Shaun Evans steps in to John Thaw's shoes to play the younger version of Colin Dexter's iconic character. 

Set in 1965, the story follows the hunt for a missing schoolgirl which draws Endeavour Morse back to the place which will ultimately shape and define his destiny – Oxford. Deep in a full-blown murder investigation and led by Detective Inspector Fred Thursday, Endeavour finds himself side-lined, discredited and at a dead end. Will he risk it all in the hunt for a truth that could haunt him for the rest of his days?

A new kind of killer haunts the Oxford twilight - he appears to strike at random, but Endeavour uncovers an underlying method to the staging of the crimes.
