Yasmin is the daughter of Bengali immigrants to Britain. She and her fiance Joe are both trainee doctors and as wedding plans advance, so too does the merging of their families, but Joe's mother Harriet is a famous feminist whose lifestyle is anathema to Yasmin's parents. As the two young people grow increasingly apart, Yasmin's mother is brought under Harriet's spell- with impacts that reverberate in previously unimaginable ways and change everything.
