Young Hyacinth (2016)

In the late 1950s, Hyacinth works as a maid to Dulcie and Claude Cooper-Smith and tries to pass off Daddy's alcoholism as the effects of his war wound--not that it fools her sisters: long-suffering lock-keeper Daisy; promiscuous Rose; and Violet, who knows how to catch a rich man. When Dulcie learns of her husband's infidelity and takes a lover herself, Hyacinth walks in on her but displays total discretion, stating that she wants a gentleman as a spouse. Her boyfriend William could fit the bill, but Daddy predictably scuppers the relationship.
