S2·E6 Episode 6

As heroin hits the streets of Manchester for the first time, CID and DCI Hunt want culprits for the smuggling, the dealing and ensuing violence, which becomes difficult when Annie is kidnapped by the smugglers. As Sam tries to get to the source of the influx of this deadly drug, he finds himself intractably drawn to a beautiful young woman who was witness to a heroin-related shooting - and who, he later realises, is the future mother of his 2006 girlfriend. At the same time, Sam's 'visions' reveal that his girlfriend has decided to stop visiting him in hospital, as she can't keep waiting for him to wake up.
