Flowers is an imaginative, cinematic show about an eccentric and dysfunctional family struggling to hold themselves together. Maurice (Julian Barratt), the author of illustrated children’s books The Grubbs, and music teacher wife Deborah (Olivia Colman) are barely together, but yet to divorce. As Maurice fights inner demons and dark secrets, Deborah tries to keep the family together at all costs and becomes increasingly suspicious that Maurice is in a secret homosexual relationship with his Japanese illustrator Shun (played by show creator Will Sharpe).
