Dramatic, thought-provoking and lighthearted, "The A-Word" captures an authentic portrait of a contemporary family after their young son is diagnosed with autism. The series tracks the lives of 5-year-old Joe (Max Vento); Joe's parents, Paul (Lee Ingleby, "Our Zoo," "Inspector George Gently") and Alison (Morven Christie, "Grantchester"), who struggle with parenting philosophies; his aunt and uncle, Nicola (Vinette Robinson, "Sherlock") and Steve (Greg McHugh, "Fresh Meat"), who are working through unfaithfulness in their marriage; and his grandfather, Maurice (Chris Eccleston, "The Leftovers," "Fortitude"), a recent widower and the owner of the family brewery.
