Jimmy McGovern's popular series of standalone dramas invites guest writers and well-known actors to tell modern stories about characters who have reached turning points in their lives and are on the verge of momentous change. In Eighteen, by Vivienne Harvey, an immigrant in foster care runs away when he has his application to remain in the UK declined, and so faces deportation back to Afghanistan. Rosie Cavaliero stars as a single mum to George (Leon Harrop); an endearing lad who has Down's Syndrome, and foster son, Mati (Antonio Aakeel), a refugee from Afghanistan, who has flourished since he moved in, aged seven. But, on his 18th birthday, a letter arrives that changes everything. It's a timely depiction of immigration and bureaucracy, filled with harrowing performances which deliver an emotional punch strong enough to question the meaning of humanity. Further episodes concern a mother's struggle to realise her teenage son no longer needs her; a father's tragic attempt to reconcile with his daughter; the pressures faced by a young man on a zero-hours contract; and a grieving woman who falls for the charms of a cowboy builder.
