Series 1

Sam's (John Simm) dogged pursuit of evidence brings him head to head with his DCI, Gene Hunt (Philip Glenister).

Uncertain about whether he really is in 1973, or in a coma in 2006 imagining the whole thing, Sam decides to make the best of his strange situation. But then the team arrest Kim Trent, an elusive criminal high on the CID's wanted list. When Sam realises that Gene has planted evidence to secure Trent's conviction he intervenes and releases Trent. Gene's furious. Sam believes that Trent has human rights. Gene believes that human rights are for human beings and Trent doesn't qualify, and besides, Gene's never fitted up anyone who didn't deserve it.

Having been released by Sam, Trent carries on with his spate of robberies and a young cleaner from the station, June, is critically wounded. This world suddenly seems very real and Gene's methods even more appealing. But Sam knows that losing sight of who he is and what he believes in could take him even further away from 'home'. Knowing that he has put things right, he successfully mixes his modern day knowledge, with a helping of Gene's unorthodox techniques, to nail Trent and his gang.
