Episode list

Day 1: In Northeast England, lives intersect when a baby is found abandoned in a hospital toilet, while a young Muslim commits suicide by jumping in front of a train.

The identity of the person killed by the train is revealed after a photofit is posted, but this only complicates matters as national intelligence immediately get involved. Besides the name, the police still know almost nothing about the victim, including any relationship to the abandoned baby, Michael.

Michael takes ill in the hospital and the diagnosis is suspected methadone withdrawal. A week after the murder and there are no leads. A reconstruction is staged where Laurie is annoyed by Gerry's interference and stroppy Muslim passenger Jamal Matthews accuses her of inciting Islamophobia. An old lady alerts Laurie to the disappearance of her neighbours on the day of the incident - a man and two women. Farid's shoe is found in their car but was apparently also worn by someone else. Nuss disowns Khalil to the adoption officer and soon afterwards their father,Ibra, finds images of Khalil with a Taliban-type group on his computer following Khalil's visit to Pakistan,allegedly to study. At the same time Khalil is meeting Jamal Matthews.

Nick takes Michael home and confesses to Colly, his dead wife's sister, that he wants to keep him but Didi tells Colly a child needs a mother and Nuss and Danny are in the frame for the adoption. Khalil freaks out at a royal visit and is briefly taken in by Laurie,which angers Ibra,who confronts his son with the computer photos,to be told they were from the past and that Khalil is changed. Pat meets old flame Maureen who tells him she lived next to the old lady with her friend's daughter Katie - now in Manchester and Michael's mother - and an Afghani boy. But he is not Farid as believed as the real Farid turns up to say he was his brother. Jen and Gerry get close as he goes with her to hospital,where her condition is re-diagnosed as physical degeneration and not Alzheimer's. Laurie and Mal also get close but,as Pat takes Maureen to the police to explain her innocence, Mal is hit by a car whilst pursuing Sohel, one of the train passengers.

Spolier; Reveals End. Two months later, Laurie, still limping from the accident that killed Mal,learns that Jen and Gerry are to marry. Maureen, having told the police she was on the bridge when the boy jumped but did not push him, lives with Pat. Farid, Michael's real father,is preparing to collect him from a resentful Nick and will raise him helped by Maureen.However Maureen steals Michael and takes him to Katie,his mother,who is not interested. She returns to Pat,telling him she shopped Farid for drug-dealing,causing his brother to kill himself as he was left on his own. Pat then kills her for having deserted him twice over,though Michael is safe. Khalil is imprisoned on suspicion of terrorism for having been at the camp in Pakistan and Nuss and Danny fear this will harm their adoptions chances forever.
