Haseen Dillruba follows Rani (Taapsee Pannu), a self-proclaimed fan of pulp detective novels, who finds herself at the center of a real-life murder investigation when her husband, Rishu (Vikrant Massey), dies in an explosion. The film jumps between their awkward arranged marriage and Rani's passionate affair with Rishu’s cousin, Neel (Harshvardhan Rane).

For those who accessed the film via mainstream OTT (or the shadow libraries like Filmyzilla), the story remains the same. Set against the dusty, vibrant backdrop of Jwalapur (a small town in North India), Haseen Dilruba follows Rani (Taapsee Pannu), a fiery, sexually assertive woman, and her meek, safety-obsessed husband Rishu (Vikrant Massey).

: The franchise frequently features themes of murder, obsession, and physical harm.
