Based on Monica Ali's acclaimed 2003 novel, the film follows the evolution of plain 18-year-old Nazneen (Tannishtha Chatterjee) who lives a sheltered life with an unpleasant middle-aged husband (Satish Kaushik) in 1980s London. She stands in stark contrast to her free-spirited sister (Zafreen) until a Muslim radical (Christopher Simpson) takes her out of her shell and wins her heart.
