About this programme
Police drama, starring John Simm. Sam experiences visions that seem to suggest a return to the 21st century, but wakes to find himself still stuck in 1973. His mood lifts when he comes face to face with the younger version of a killer he arrested in 2006 and realises he has the chance to prevent a crime before it happens - but his unorthodox methods surprise colleagues at the station. With Philip Glenister and Marc Warren.
