Based on the classic book series by Richmal Crompton, this BBC show is a "charming romp" (The Guardian, UK) about mischievous 11-year-old William Brown (Daniel Roche, Outnumbered) in 1950s England. Rebecca Front (Humans), Daniel Ryan (Home Fires), and Lily James (Cinderella) are William's exasperated family, forever contending with his misadventures, in this BAFTA-winning drama.
