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.
