Tyler has visions of someone disrupting his life support system in 2006, and encounters who he thinks is the same assailant in 1973, running a gambling syndicate and protection racket. Recognising the man as a killer he failed to stop in the future, Tyler is prepared to go to any lengths to make sure his life is not threatened and the man doesn't kill his original victim.

On an assignment to return a career safe breaker from prison for further questioning, Tyler, Ray and Chris are attacked by robbers and the man who they were taken in for questioning is broken out. Is a local gangster to blame, or is there more going on than meets the eye... specifically, was the crime actually arranged by Gene's old mentor? Meanwhile, Sam tries to break in the first black detective in the department, a man who will later become Sam's mentor when he first joins the police force.

The team receive a bomb warning, claiming the IRA has planted a car bomb in Manchester. Being from 2006, Sam realises the bomb warning reported doesn't fit with his understanding of IRA methods. However, when Sam's modern know-how fails and nearly kills Ray, the rest of the department shun his line of investigation to focus on an Irish socialist group. At the same time, Sam's visions of the future suggest that he may have suffered brain damage, affecting his higher reasoning, from having been in a coma for so long.
