Show of the week: White Heat

Sensitive performances buoy this thoughtful six-part drama series, which follows seven friends across several decades, beginning when they shared a flat in 1960s London. In the premiere, a death in the group triggers a flashback that reveals how this diverse assortment of people joined together in 1965 in an experiment with communal living. The dialogue is sometimes clichéd, but Claire Foy (Little Dorrit) anchors the series as a young woman who owes her social and sexual awakening to the radical son of a Tory member of Parliament. Wednesday, May 9, at 10 p.m., BBC America
