The Men's Room (1991)

Synopsis
Based on a novel by Ann Oakley, the British miniseries The Men's Room starred Harriet Walter as officer worker Charity Walton. Despite her status as wife and mother, Charity entered into a romantic liaison with a coworker named Mark Carleton (Bill Nighy). The ensuing consequences not only exacted a great emotional toll on Charity, her husband, her lover, and his wife, but also exposed the hypocrisies of the good-old-boy office mentality. The five 50-minute episodes of The Men's Room were telecast by BBC2 in 1991. ~ Hal Erickson, All Movie Guide
